© 2020 IEEE. We examine the relationship between the minimal robust positively invariant sets, mRPI, of discrete-time switched and time-delay systems. Assuming the existence of the mRPI sets for each system, we show that the mRPI set of a finitely many sub-system switched system is strictly contained in the mRPI of a corresponding time delay system. We further demonstrate that the minimal convex robust positively invariant set of either a time-delay or, the corresponding, switched system is the convex hull of the mRPI of either system.

© 2020 IEEE. This paper investigates discrete-time multi-agent single-input consensus systems in regard to the control design and scalability. In particular, we propose a new controller design that handles any number of connected agents and various communication structures, belonging to a defined group of graphs, without the need to change the individual controller of the agents. We give a rigorous proof that the resulting system achieves consensus.

© 2020 IEEE. Multi-agent consensus systems have been investigated in the continuous-time setting in regard to the control design, their scalability, and their robustness to interference. The discrete-time setting lacks the same depth of investigation. This paper investigates discrete-time multi-agent consensus systems. In particular, we propose a new controller design. The design uses a linear controller that is independent of the number of agents connected and imposes a single constraint on the communication structure. This is a step towards a scalable multi-agent consensus system that allows simple connection of additional agents without readjustments to the controller.

© 2020 IEEE. Matrix Converter is an attractive choice for motor drives with weight/size restrictions and high efficiency requirements, such as mobile mining vehicles. However, the use of Matrix Converters requires addressing the problem with input resonance. Variable length of the trailing cables used with mining vehicles makes the existing solutions for input resonance suppression ineffective. This paper addresses this problem by proposing and analyzing two solutions for input resonance suppression in Matrix Converters: a solution based on the output spectrum shaping, and a solution based on a direct synthesis of the optimal switching matrix. The paper shows that both solutions achieve the goal, but have different implications for practical implementation. The results are supported by extensive simulations.

© 2020 IEEE. Matrix Converters (MC) have prominent advantages in AC/AC power conversion applications, for example, in aerospace and surface transport. However, due to a tight interconnection between its input and output, it is difficult to achieve satisfactory performance on both sides, simultaneously. This paper proposes a novel, optimisation based, design approach for the modulation (duty cycle) matrix associated with the MC. Under this approach, the entries of the modulation matrix are used as decision variables in a quadratic optimisation programme. The optimisation combines control requirements both at the input and output sides of the converter in a non-conflicting manner. The paper includes simulation results, which demonstrate that the proposed solution complies with the objectives of both sides. Thus high quality tracking at the MC output is achieved simultaneously with input resonance suppression and power factor control at the MC input. An estimate of the computational load is provided which suggests that a real-time implementation is easily achievable.

© 2017 IEEE. Progressive increase of distributed generation penetration levels into the power grid has motivated studies on network stability and control methods in order to maintain the grid in operational conditions. A key challenge to better study features of the power grid is to have a reliable network model under different circumstances. In this paper, we derive a structured nonlinear model for the network and then propose an approximate model that captures the system nonlinearities. We then design voltage control functions and derive a dynamic network model with embedded controllers. We analyse voltage stability of the controlled network for both the exact and approximate models. In particular, we give conditions for the voltage to ultimately lie within quantifiable bounds for both models. This result also allows to compute a bound on the difference between the exact and approximate model voltages.

© 2015 IEEE. In this paper we study frequency stabilisation in inverter-based microgrid systems with primary droop controller and three types of secondary control strategies. Particularising the microgrid to the case of two inverter buses, we propose structured models for which frequency regulation, ultimate bounds and an estimate of the region of attraction associated with the ultimate bound set are obtained in closed-form analytical expressions.

© 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd. All rights reserved.This paper analyses conditions for computing invariant sets for Lure-type nonlinear systems via two different approaches, by bounding the nonlinear terms and by embedding the nonlinear system in a linear parameter varying (LPV) model. Furthermore, we show that by an appropriate redefinition of the system's nonlinear terms, the sets obtained by both approaches can be made identical. These methods can be used to compute sets characterising faultless (nominal) and faulty system behaviour, which are applicable for fault diagnosis under specific conditions that guarantee their separation. We also present a simple mechanism for sensor fault estimation and controller compensation, thus resulting in a closed-loop fault tolerant control system. An example of a pendulum system is provided to illustrate the proposed approach.

© Springer International Publishing Switzerland 2015. In this contribution we propose a fault tolerant control (FTC) scheme to compensate for sensor faults in multisensor fusion-based control of linear parameter varying systems. The scheme consists of a closedloop system with an estimator-based feedback tracking controller that combines healthy sensor-estimator pairings via a fusion algorithm. Faulty sensors are detected and discarded based on a set separation criterion, which considers both model uncertainty and system disturbances. We ensure the preservation of closed-loop system boundedness for a wide range of sensor fault situations and for the whole domain of plant model uncertainty. To illustrate the performance of the proposed FTC strategy, a flexible joint robotic arm example is presented.

© Springer International Publishing Switzerland 2015. In this paper, we first provide a mathematical description and proof for the robust stability of systems with convex polytopic uncertainty through the construction of attractive invariant sets. Then, we present the problem of estimating the convergence time to arbitrarily tight over-approximations of an invariant set, from both a known initial condition and for initial conditions belonging to a convex polytopic set. We then propose various analytical and numerical methods for computing the aforementioned convergence time. Finally, a number of numerical examples, including a flexible link robotic manipulator, are given to illustrate the results.

© 1999 EUCA. Model predictive control is a well established strategy for dealing with saturating actuator problems. The essential feature of the method is a receding horizon quadratic optimal control problem which is solved subject to input constraints. On the other hand, anti-windup methods are ad-hoc procedures which achieve input saturation in an instantaneous fashion. Both methods are known to perform well in practice and each has its strong advocates. In this paper, we explore connections between the methods. In particular, we show that there are cases in which anti-windup schemes are identical to MPC schemes. In other cases, we show that anti-windup has performance which is close to that of MPC strategies.

© 2015 Engineers Australia. Icing is regarded as a severe structural alteration affecting unmanned aerial vehicles (UAVs), since ice accretion on wings and control surfaces modifies the aircraft shape resulting in altered controllability and performance of the vehicle. We study the problem of detection of icing and estimation of its 'severity' factor in longitudinal control of UAVs. We propose to employ a bank of unknown input observers (UlOs), each designed to match a model of the aircraft under a particular level of icing taken from a quantisation of the icing's severity factor range of variation. The UIO design exploits the change in equilibrium conditions, caused by the icing effect, to identify a direction in the observer estimation error space that allows for aircraft icing detection and estimation. By selecting at each time the observer from the bank that yields the smallest value of a suitable residual signal, the icing severity factor can be estimated with an accuracy that is inversely proportional to the size of the quantisation level.

© 2015 Engineers Australia. This paper is concerned with linear parameter varying (LPV) fault tolerant control (FTC) systems reconfigured using virtual actuators. Most works dealing with FTC of LPV systems in general, and in particular using virtual actuators, assume perfect knowledge of the 'varying parameter' of the LPV system description at all times. In this paper, for LPV systems with convex polytopic modelling description, we derive conditions for closed-loop stability of the overall virtual-actuator based FTC system when the varying parameter is not exactly known but measured with bounded errors.

© 2015 Engineers Australia. In this paper, we present a fault tolerant control (FTC) scheme for linear parameter varying systems that utilises multiple sensor switching to compensate for sensor faults. The closed-loop scheme consists of an estimator-based feedback tracking controller and sensor-estimate switching strategy which allows for the recovery of faulty sensors. The switching mechanism tracks the transitions from faulty to healthy behaviour by means of set separation and pre-computed transition times. The selected sensor-estimate pairing is then reconfigured based on available healthy sensors. Under the proposed scheme, preservation of closed-loop system boundedness is guaranteed for a wide range of sensor fault situations. An example is presented to illustrate the performance of the FTC strategy.

© 2014 Engineers Australia. A recently proposed set-theoretic approach to fault diagnosis is based on membership of residual signals to (invariant) sets that characterise healthy and faulty system behaviour. Correct diagnosis is achieved if the relevant sets are disjoint. Tighter sets that allow separation for a larger class of faults are hence desirable within this approach. In this paper, we investigate methods to compute invariant sets for a Lure system from two different perspectives: by bounding the nonlinear terms and by embedding the nonlinear system in a linear parameter varying (LPV) model. To analyse and compare the methods, we develop a scalar and a second-order system case, and provide an example of a latter system. The results show that both approaches can be used for fault diagnosis and yield comparable performance for this type of systems under specific conditions.

© 2009 EUCA. This paper deals with the problem of obtaining fault-tolerant guarantees of a multi-sensor switching strategy for longitudinal control. The strategy selects, at each instant of time, the sensor (belonging to a collection of sensors) that provides the best closed loop performance, as measured by a control-performance criterion. It is assumed that each sensor has an associated feedback controller that has been designed such that the sensor-controller pair stabilises the closed loop system under normal operation conditions. Recent refinements for constructing ultimate-bound invariant sets allow obtaining less conservative fault-tolerant guarantees. Stability of the switching system under fault-free operation conditions and under presence of sensor failures are established in the main results of this paper.

© 2009 EUCA. This paper presents the properties of a new variant of model predictive control called Reduced Parameterisation Model Predictive Control (RPMPC). The new algorithm uses the structure of the null controllable set of input constrained unstable systems to produce a closed-loop system with a region of attraction that is an arbitrarily close approximation to this set. We show that the RPMPC algorithm converges in a finite number of iterations and we establish stability of the resulting closed-loop system. In addition, we present a rigorous worst case complexity analysis together with average computational tests. Both these studies show that for long horizons RPMPC has a lower computational requirement than that of standard MPC.

© 2009 EUCA. Model Predictive Control (MPC) is a popular advanced control strategy that is implemented by determining an optimal control sequence at each time step. One of the major contributors to MPC's computational complexity is the length of the control sequence or, equivalently, the number of optimisation parameters. This paper analyses the null controllable sets, and their related finite horizon approximation, of a class of unstable systems. The analysis reveals that the same control action can be obtained using a much smaller set of control moves via a technique which we term reduced parameterisation.

© 2007 EUCA. In this paper we investigate the fault tolerance properties of a multisensor switching strategy previously proposed by the authors. We show that closed-loop stability of the resulting switching scheme is guaranteed in the presence of faulty sensors if a set of conditions on the system parameters (such as bounds on the sensor noises, maximum and minimum values of the reference signal, etc.) is satisfied. This constitutes an important step in enhancing and broadening the applicability of the proposed multisensor scheme since it provides guaranteed properties such as fault tolerance and robust closed-loop stability under sensor failure. The results are applied to the problem of automotive longitudinal control.

We present a new control design method which guarantees any prespecified componentwise ultimate bound on the state of multiple-input systems with matched perturbations. The method is based on eigenstructure assignment by state feedback and utilises a componentwise bound computation procedure recently proposed by the authors. This procedure exploits both the system and perturbation structures by performing componentwise analysis, thus avoiding the need for bounds on the norm of the perturbation. We present examples which illustrate the simplicity and generality of the method.

Advanced design aims to achieve the best possible performance subject to operational constraints. Such questions can be formulated as optimization problems. The advantages of using an explicit optimization formulation include clear articulation of performance trade-offs and the provision of a clear basis for quantitative comparison of different strategies. In this paper we will briefly review aspects of modern optimization. We will also show how these tools can be deployed in scheduling, estimation and control. We will illustrate the ideas by examples drawn from the mining, mineral and metal processing field. Copyright © 2007 IFAC.

An output-feedback control scheme is proposed based on the Certainty Equivalence [CE] principle and explicit solutions to the problem are investigated. It is assumed that the full state of the system is not measured and, instead, a measured output corrupted with measurement noise is available. It is also assumed that the control inputs are subject to polyhedral constraints. The CE control implementation uses a receding-horizon control law to compute the control action based on a state estimate obtained from a moving horizon state estimator. The structure of the solution is given by a piece-wise affine function of the parameters of the problem and a partition of the parameter space into polyhedral regions. The parameterized regions and coefficients of the piece-wise affine function can be pre-computed offline, allowing a simplified approach in implementing the output-feedback controller online. © 2006 IEEE.

This paper investigates the structure present in constrained linear state estimation problems formulated as a quadratic optimization program subject to linear inequality constraints. Polyhedral constraints on the system disturbance, the measurement noise, and the initial state are considered. The result interprets the measurement data and prior estimate as parameters and the parameter space is partitioned into multiple regions. Within each region the state estimate can be calculated as a piece-wise affine function of the measurement data and prior estimate. The parameterized regions and coefficients of the piece-wise affine function can be precomputed offline allowing a simplified approach in implementing a moving horizon estimation scheme.

We present a receding horizon control algorithm for compensation of backlash at the input of a stable linear system under control rate constraints. The problem is first posed as a receding horizon optimal control problem by modelling backlash as a piecewise affine system with a state space partition consisting of three regions. This optimal control problem involves solving, at each step, 3N quadratic programmes, where N is the optimisation horizon. As an alternative to solving the quadratic programmes, we propose a strategy based on a recently devised suboptimal receding horizon control algorithm which utilises a singular value decomposition of the Hessian of the quadratic programme. This alternative strategy leads, at the cost of some performance degradation, to much smaller computational load since a feasible rather than optimal solution has to be obtained at each step.

© 2003 EUCA. The solution to constrained linear model predictive control (MPC) problems can be pre-computed off-line in an explicit form as a piecewise affine (PWA) state feedback law defined on polyhedral regions of the state space. Even though real-time optimization is avoided, implementation of the PWA state-feedback law may still require a significant amount of computation due to the problem of determining which polyhedral region the state lies in. In this paper, a neural network approach to this problem is investigated.

© 2003 EUCA. In this paper we consider an alternative approach to implementing Model Predictive Control (MPC). We show that solving a class of quadratic programming (QP) problems is equivalent to solving a class of well-posed nonlinear algebraic loops. These algebraic loops are closely related to that found in static anti-windup synthesis. It therefore follows that certain classes of MPC can be implemented in a form that is a direct generalisation of the standard anti-windup structure. Implementations for classes of MPC are then derived for both regulator and tracking problems. Several alternative iterative algorithms for solving the algebraic loop are then presented. Some simulation results are also provided, with an example computational comparison to active set and interior point based MPC.

We present two redesigns to robustify backstepping control laws against dynamic uncertainties at the input of the plant. In the first redesign we construct a passivating control law from a CLF obtained by backstepping. In the second redesign we simplify the passivation redesign which becomes cumbersome for high order systems. We also review the two main versions of backstepping: cancelation and LGV-backstepping, and compare their stability margins.
