Â© 2015 IEEE. This paper proposes a switching control strategy for formation maneuvering control of multiagent systems with guaranteed collision avoidance and connectivity maintenance properties. The control strategy consists of three parts: formation maneuvering, collision avoidance, and connectivity maintenance control. We adopt the idea of using complex Laplacian for formation maneuvering control, which gives rise to one degree of freedom in scaling the size of the achievable formations and thus enables collision avoidance and connectivity maintenance possible in the meantime. Simulation results are provided to demonstrate the effectiveness of the control strategy.

Â© 2014 Chinese Automatic Control Society and Wiley Publishing Asia Pty Ltd. This paper investigates the LQG control problem for networked control systems (NCSs) with packet losses, where the packet losses are considered to appear in both the sensortocontroller channel and controllertoactuator channel. Bernoulli random processes are used to describe the packet losses in the two channels. Two simple compensation schemes are explored for state estimation with missing measurements in which the input of the plant is set to zero if a packet is lost, and the holdinput strategy, in which the previous input is used with packet dropout. The optimal static controller gains and the critical loss probabilities for the two schemes are presented, and their performances are compared in terms of numerical simulations. The conclusion is that neither of the two schemes can be claimed to be superior to the other, as the stability regions of the two strategies are reversely complemented to each other whether for the scalar or vector example.

Â© 2015 IEEE. This paper is concerned with the stabilization problem for discretetime stochastic systems with multiplicative noise and multiple input delays. Our approach is based on a reduction technique, by which the system under consideration is converted into a delayfree system. The necessary and sufficient stabilization condition for stabilization and the associated feedback controller are characterized via a generalized Riccati equation.

Â© 2015 Technical Committee on Control Theory, Chinese Association of Automation. This paper focus on the consensusability of highorder multiagent systems (MASs) with uniform constant communication delay in an undirected network. We show that N agents achieve consensus if and only if N  1 timedelay subsystems associated with the eigenvalues of the Laplacian matrix are simultaneously asymptotically stable. By employing a linear matrix inequality (LMI) method, we present a sufficient condition for MASs to reach consensus. Also we consider the consensus condition of firstorder integrator system by using frequency domain analysis.

Â© 2015 Technical Committee on Control Theory, Chinese Association of Automation. This paper studies a dynamic state estimation problem for power systems, which can be seen as the quasistatic systems. The state vector of each subsystem (called node) in power networks is expressed by measurements. Based on a distributed maximum a posteriori (MAP) estimation technique, a fully distributed state estimation method is presented to update the local state at each time instant. Also, the assumption of local observability of every node is no longer needed. Tests on the IEEE 118bus system are used to show the performance of the proposed approach and compare its results with a centralized state estimation method providing the optimal state estimate for the entire power networks, a local state estimation method using the edge measurements as the local measurements to estimate its local state, and a distributed static state estimation algorithm.

Â© 2015 Technical Committee on Control Theory, Chinese Association of Automation. The purpose of this paper is to study stabilization problem of linear timeinvariant systems subject to stochastic multiplicative uncertainties and time delays. We consider a structured multiplicative perturbation which consists of static, zeromean stochastic processes and we assess the stability of system based on meansquare criteria. The meansquare stabilization problem for multiinput multioutput systems generally requires solving an optimization problem involving the spectral radius of a certain closed loop transfer function matrix. This problem in general is nonconvex and by and large unresolved, only approximate solutions are available based on numerical algorithms resembling to the DK iteration for Âµsynthesis. Our main contributions include the fundamental conditions, both necessary and sufficient, which insure that the multiinput multioutput minimum phase systems can be stabilized by output feedback in the meansquare sense. We provide a complete, computationally efficient solution in the form of a generalized eigenvalue problem readily solvable by means of linear matrix inequality optimization. For conceptual insights, limiting cases are analyzed in depth to characterize and quantify explicitly how the directions of unstable poles may affect the meansquare stabilizability of multiinput multioutput systems.

Â© 2015 Technical Committee on Control Theory, Chinese Association of Automation. In this paper, we propose a distributed algorithm for the dynamic economic dispatch problem (DEDP) in a smart grid scenario. Different from the static economic dispatch problem (SEDP), the DEDP aims at minimizing the aggregate operating costs of a group of generators over a time period with ramp rate constraints. The proposed algorithm is based on the average consensus algorithm on undirected graphs and the alternating direction method of multipliers (ADMM). Our algorithm is distributed in the sense that no leader or master nodes are needed, while all the nodes (generators) conduct local computation and merely communicate with their neighbors. Convergence analysis shows that the proposed algorithm converges to the optimal solution.

Â© 2014 TCCT, CAA. In the recent years, condition monitoring of the train suspension system draws a lot of attention because it acts as the guardian to ensure the safety of the train and provides more information for the overhaul. Meanwhile, it makes the train runs steadily and reduces the operating costs. This article focuses on the identification of the train suspension parameters using a crosscorrelation technique. We show that the new method can effectively estimate the coefficients of both the spring and the damping coefficients. Simulation results are presented to show the effectiveness of this method.

Â© 2014 TCCT, CAA. Plugin hybrid electric vehicles (PHEV) tend to become more widespread in the next decades. However, large penetration of PHEVs will overload the distribution system. In smart grid, the charging of PHEVs can be controlled to reduce the peak load, which is known as demand side management (DSM). In this paper, we focus on the impact of PHEV charging on lowvoltage transformers. The objective is to flatten the load curve of lowvoltage transformers, while each consumer's requirement for their PHEV to be charged to the required level by their specified time is satisfied. We first formulate it as a convex optimization problem and then propose a distributed waterfillingbased algorithm to solve it. Proofs of optimality and numerical simulations are given to demonstrate the effectiveness of our algorithm.

Â© IFAC. The paper studies the formation merging problem for a leaderfollower network. That is, how to control a team of agents called followers so that they are merged with a team of agents called leaders to form a larger globally rigid formation. Under the premise that a group of leaders move in a globally rigid formation with their synchronized velocity known to the followers, we show that the followers can asymptotically merge themselves to the formation for arbitrarily initial configurations. Each follower selects its neighbors and also its control law according to the target formation they aim to achieve and thus it allows directed and timevarying switching topologies. It is shown that a globally rigid formation can be merged asymptotically for the leaderfollower network in a setup with directed and timevarying graphs if and only if every follower frequently has a joint path from at least a leader.

Â© 2014 IEEE. This paper proposes a simple, distributed control protocol for multiagent systems with relative sensing capability over a directed network to achieve an affine formation. In contrast to the linear consensus protocol, the control protocol in this paper takes both positive and negative weights that partially encode the target formation shape and is thus able to achieve a formation pattern rather than just consensus. Having possibly negative weights in a graph, the associated Laplacian is called the generalized Laplacian. The connection between the generic rank property of the generalized Laplacian and the connectivity of a directed graph is established, based on which a necessary and sufficient graphical condition is developed to ensure the emergence of an affine formation by the proposed distributed control protocol.

Â© 2014 IEEE. This paper studies the formation maneuvering control problem for a network of agents with the objective of achieving a desired group formation shape and a constant overall group maneuvering velocity. A fully distributed approach is developed to solve the problem. That is, a control law is proposed for each agent in the network, with its parameters capable of being designed in a distributed manner, and is implementable locally via relative sensing and communication with neighbors. Necessary and sufficient conditions regarding a critical control parameter are obtained to guarantee the globally asymptotic convergence of the overall system for both the singleintegrator kinematics case and the doubleintegrator dynamics case.

Â© IFAC. This paper studies the problem of countering the fluctuations of renewable power supply in smart grid. A fully distributed algorithm to control a network of thermostatically controlled loads (TCLs) is proposed to match, in real time, the aggregated power consumption of the TCLs and the forecast power supply. The algorithm is developed by converting the control problem into a consensus problem of individual utility functions. We then show that the problem is equivalent to a convex optimization problem and an algorithm based on distributed bisection method is presented to solve the problem. The proposed algorithm converges fast and is fully distributed, requiring only local information for each TCL and limited communication with neighboring TCLs, yet the available power supply is fairly dispatched among different TCLs. A numerical example is given to illustrate the effectiveness of the algorithm when applied to a network of variablefrequency airconditioners (VFACs).

Â© 2014 IEEE. Economic dispatch problem (EDP) is an important optimization problem in power systems, aiming at minimizing the aggregate cost of a group of power generators, which cooperatively generate a given amount of power within their individual capacity constraints. In this paper, we present an average consensus based bisection approach for the EDP with quadratic cost functions, which is fully distributed and especially desirable in a smart grid scenario. Under the connected topology condition, we show that the proposed iterative solution converges to the globally optimal solution of EDP, without the need for a central decision maker or a leader node. Finally, numerical simulation based on the IEEE 14bus system is given to show the performance of the approach.

Â© 2009 EUCA. In this paper we investigate the stability of discretetime linear timeinvariant systems subject to finitelevel logarithmic quantized feedback. Both state feedback and output feedback are considered. We develop an LMI approach to estimate, for a given controller and a given finitelevel quantizer, a set of admissible initial states and an associated attractor set in a neighborhood of the origin such that all state trajectories starting in the first set will converge to the attractor in a finite time and will never leave it. Furthermore, when these two such sets are a priori specified, we develop sufficient conditions for designing a suitable state or output feedback controller, along with a finitelevel logarithmic quantizer.

Â© 2014 IEEE. The paper studies the formation control problem for distributed robot systems. It is assumed each robot only has access to local sensing information (i.e. The relative positions and IDs of its neighbors). Taking into consideration physical sensing constraints (e.g. limited sensing range) and the motion of the robots over time, it may be noted that the sensing graph for the system is directed and timevarying. This presents a challenging situation for formation control. As an initiative attempt to study this challenging situation, we suppose the sensing graph switches among a family of graphs with certain connectivity properties, under which a switching linear control law is then proposed. We show that for arbitrary dwell times or average dwell times, the proposed control law with properly designed control parameters can ensure global convergence to a desired formation shape. The proposed formation control law can be implemented in a distributed manner while the design of certain control parameters requires some global information.

Â© IFAC. We study a networked state estimation problem for a linear system with multiple sensors, each of which transmits its measurements to a central estimator via a lossy communication network for computing the minimum meansquareerror (MMSE) state estimate. Under a general Markov packet loss process, we establish necessary and sufficient conditions for the stability of the estimator for any diagonalizable system in the sense that the mean of the state estimation error covariance matrix is uniformly bounded. For the secondorder systems under an i.i.d. packet loss model, the stability condition is expressed as a simple inequality in terms of openloop poles and the packet loss rate.

Â© IFAC. In this paper, the state estimation problem for continuoustime linear systems with two types of sampling is considered. First, the optimal state estimator under periodic sampling is presented. Then the state estimator with eventbased updates is designed, i.e., when an event occurs the estimator is updated linearly by using the measurement of output, while between the consecutive event times the estimator is updated by minimum meansquared error criteria. The average estimation errors under both sampling schemes are compared quantitatively for first and second order systems, respectively. A numerical example is given to compare the effectiveness of two state estimators.

Â© IFAC. A recently proposed Bayesian tracking procedure for sensor networks approximates the update equation, which involves nonlinear measurements, with a simple equation using the maximum likelihood (ML) estimate of the unknown state. This approach permits a numerically efficient implementation of the tracking procedure, and is suitable for a distributed implementation. In this paper we study the extent to which this approach approximates the theoretical Bayesian solution. We provide conditions to guarantee that the approximation becomes asymptotically exact, as the number of nodes becomes large. This result is relevant in applications where each sensor obtains a measurement with limited information about the state, but a large number of sensors is available. We apply our result to a case study, and present numerical simulations, showing that the approximation error becomes negligible for a relatively small number of nodes.

This paper studies optimal control designs for networked linear discretetime systems with quantization effects and/or fading channel. The quantization errors and/or fading channels are modeled as multiplicative noises. The H2 optimal control in meansquare sense is formulated. The necessary and sufficient condition to the existence of the meansquare stabilizing solution to a modified algebraic Riccati equation (MARE) is presented. The optimal H2 control via state feedback for the systems is designed by using the solution to the MARE. It is a nature extension for the result in standard optimal discretetime H2 state feedback design. It is shown that this optimal state feedback design problem is eigenvalue problem (EVP) and the optimal design algorithm is developed. Â© 2014 IEEE.

Â© 2014 TCCT, CAA. This paper studies optimal regulation problem for networked linear discretetime systems with fading channel. The uncertainties in fading channels are modeled as multiplicative noises. The regulation performance is measured by a quadratic function. The optimal state feedback is designed by the meansquare stabilization solution to a modified Algebraic Riccati equation (MARE). The necessary and sufficient condition to the existence of the meansquare stabilization is presented in terms of the inherent characterizations of the systems. It is a nature extension for the result in standard optimal discretetime linear quadratic regulation (LQR) problem. We also show that this optimal state feedback design problem is an eigenvalue problem (EVP). And then a design algorithm is developed for this optimal control problem.

The paper presents a linear approach for formation control of multiple autonomous agents in ddimensional space. The generalized notion of graph Laplacian, associated to a graph with possibly negative weights on the edges, is introduced aiming to solve the formation problem of controlling a network of point agents to form a given pattern (including rotation, translation, and scaling). By assuming the number of agents is larger than d + 1, we derive that a linear distributed control law exists for this purpose if and only if certain algebraic conditions hold (or equivalently, the graph is globally rigid). Next, it is shown that the generalized graph Laplacian used to stabilize the formations can be obtained by solving a convex optimization problem. Further results are also provided to reveal the conditions under which the attained formations are congruent to or just translations of the desired one. Â© 2013 IEEE.

In this paper, we study the problem of finite horizon Kalman filtering for systems involving a normbounded uncertain block. A new technique is presented for robust Kalman filter design. This technique involves using multiple scaling parameters which can be optimized by solving a semidefinite program. The use of optimized scaling parameters leads to an improved design. Also proposed is a recursive design method which can be applied to realtime applications.

Â© SpringerVerlag Berlin Heidelberg 1998. Face recognition is an important research area with many potential applications such as biometric security. Among various techniques, eigenface method by principal component analysis (PCA) of face images has been widely used. In traditional eigenface methods, PCA was used to get the eigenvectors of the covariance matrix of a training set of face images and recognition was achieved by applying a template matching scheme with the vectors obtained by projecting new faces along a small number of eigenfaces. In order to avoid the time consuming step of recomputing eigenfaces when new faces are added, we use a set of modules to generate PCA based face representation for each subjects instead of PCA of entire face images. The localized nature of the representation makes the system easy to maintain and tolerant of local facial characteristic changes. Results indicate that the modular scheme yield accurate recognition on the widely used Olivetti Research Laboratory (ORL) face database.

Many different types of adaptive or "universal controllers", capable of dealing with a very broad range of linear timeinvariant systems, have been proposed. One class of such controllers uses switching between a unite, or at least countable, number of fixed controllers until stability is detected. Such controllers are very attractive from a theoretical viewpoint, in providing stabilization and asymptotic performance for a broad class of plants. However, such controllers are also known to have very poor transient properties, due to the long time required to search for a stabilizing feedback. The key contribution of this paper is to introduce the "method of localization" which can greatly improve the speed of the search. The method is described for linear timeinvariant discrete time systems of known nominal order, with disturbances and noise present. Analysis and simulations demonstrate the potential for greatly improved transient performance.

This paper studies the structured singular value (Âµ) problem with real parameters bounded by an lp norm. Our main result shows that this generalized Âµ problem is NPhard for any given rational number p Â¿ [1, 8], whenever Â¿, the size of the smallest repeated block, exceeds 1. This result generalizes the known result that the conventional Âµ problem (with p = 8) is NPhard. However, our proof technique is different from the known proofs for the p = 8 case as these proofs do not generalize to p Â¿ 8. For Â¿ = 1 and p = 8, the Âµ problem is known to be NPhard. We provide an alternative proof of this result. For Â¿ = 1 and p finite the issue of NPhardness remains unresolved. When every block has size 1, and p = 2 we outline some potential difficulties in computing Âµ.

Given a timedelay system, we are interested in finding new robust stability conditions for the system. We apply the integral quadratic constraint approach to obtain two results which allow us to test the robust stability using the linear matrix inequality technique. Both results give an estimate of the maximum timedelay which preserves robust stability. The first result is simpler to apply while the second one gives a less conservative robust stability condition.

We consider the relative stability of time invariant and time varying unnormalized lattice filters. First, we consider a set of lattice filters whose reflection parameters ai, obey ai = di, and provide necessary and sufficient conditions on the di that guarantee that each time invariant Lattice in the set has poles inside a circle of prescribed radius 1/Â¿ < 1, i.e. they are relatively stable with degree of stability ln Â¿. We also show that the relative stability of the whole family is equivalent to the relative stability of a single filter obtained by fixing each ai to di, and can be checked with only the real poles of this filter. Counterexamples are given to show that a number of properties that hold for stability of LTI Lattices do not apply to relative stability verification. Second, we give a diagonal Lyapunov matrix that is useful in checking the above pole condition. Finally, we consider the time varying problem where the reflection coefficients vary in a region where the frozen transfer functions have poles with magnitude less than 1/Â¿, and provide bounds on their rate of variations that ensure that the zero input state solution of the time varying Lattice decays exponentially at a rate faster than 1/Â¿' > 1/Â¿.

This paper considers the robust strict positive real(SPR) problem for a family of plants of the form G(s,q) = N(s, q n)D 1(s, q d)a, where N(s, q n) and D(s,q d) are multiaffin... [more]
This paper considers the robust strict positive real(SPR) problem for a family of plants of the form G(s,q) = N(s, q n)D 1(s, q d)a, where N(s, q n) and D(s,q d) are multiaffine in uncertain parameters q n and q d, respectively, and a > 0. In the discretetime setting, this problem plays an important role in digital quantization. Several results are presented. First, we prove that this plant family is robustly SPR if and only if all 'corner plants' in the family are SPR. Secondly, we show that, if this plant family is robustly SPR, it admits a multiaffine Lyapunov matrix for the KalmanYakubovicPopov (KYP) inequality, i.e, the Lyapunov matrix is multiaffine in the uncertain parameters. This result is useful in robustness analysis of timevarying systems. Thirdly, we relate the robust SPRness of this plant family to the robust strict bounded realness (SBRness) of a plant family involving the inverse of N(s,q n)D 1(s,q d). We show that multiaffine Lyapunov matrix for the KYP inequality of the first plant family yields a multiaffineLyapunov matrix for the bounded real inequality of the second plant family. Finally, the robust SPR problem is considered for a more general plant family with applications in circuits and communication systems.

In this paper, we investigate the use of twoterm piecewise quadratic Lyapunov functions for robust stability of linear timevarying systems. By using the socalled Sprocedure and a special variable reduction method, we provide numerically efficient conditions for the robust asymptotic stability of the linear timevarying systems involving the convex combinations of two matrices. An example is included to demonstrate the usefulness of our results.

For systems which do not have a diagonal interactor, a bicausal precompensation or static state feedback is insufficient for decoupling. Conditions are characterized under which a multiinput, multioutput (MIMO) system can be made decouplable by a diagonal dynamic precompensation. More specifically, the authors determine necessary and sufficient conditions under which diagonal dynamic precompensation exists which achieves a diagonal interactor.

A discussion is presented of recent results relating to the parametric approach to robust stability. The general problem of robust stability is defined, and a review of Kharitonovtype and edge theorems, zero exclusion results, interval matrix stability, maximal perturbation bounds, multilinear and nonlinear perturbations, time delay systems, and numerical/graphical approaches is presented. Some open research directions are indicated, and the future of the approach is discussed.

Kharitonov's theorems are generalized for the problem of socalled Kharitonov regions for robust stability of linear uncertain systems. Given a polytope of (characteristic) polynomials P and a stability region D in the complex plane, P is called Dstable if the zeros of every polynomial in P are interior to D. It is of interest to known whether D is a Kharitonov region, that is, whether the Dstability of the vertices of P implies the Dstability of P. A simple approach is developed which unifies and generalizes many known results on this problem.

A fundamental result was previously established on the zero locations of a family of polynomials. It was shown that the zeros of a polytope P of nthorder real polynomials is contained in a simply connected region D if and only if the zeros of all polynomials along the exposed edges of P are contained in D. This work was motivated by the fact that the requirement of simple connectedness of D may be too restrictive in applications such as dominant pole assignment and filter design where the separation of zeros is required. The authors extend the edge criterion of the previously study to handle any region D whose complement Dc has the following property: every point d e Dc lies on some continuous path which remains within Dc and is unbounded. This requirement is typically verified by inspection and allows for a large class of disconnected regions. The authors also allow for polynomials with complex coefficients.

The authors develop a method for adaptive stabilization without a minimum phase assumption and without knowledge of the sign of the high frequency gain. In contrast to recent work by B. Martensson (1985) the authors include a compactness requirement on the set of possible plants and assume that an upper bound on the order of the plant is known. Under these additional hypotheses, the authors generate a piecewiselinear timeinvariant switching control law which leads to a guarantee of Lyapunov stability and an exponential rate of convergence for the state. One of the main objectives of this work has been to eliminate the possibility of large state deviations associated with a search over the space of gain matrices that occurred in Martensson's study.
