Career Summary
Biography
Julio Braslavsky has been a researcher in the field of control systems theory since 1996, working with world-class groups in the field at the University of Newcastle and The University of California, Santa Barbara, USA. Braslavsky has made substantial contributions to the theory of performance limitations in filtering and control systems, on which he has coauthored the book. His main contributions include the following specific areas:
Networked control systems. Braslavsky and coworkers developed a new framework based on signal-to-noise ratio constrains for the analysis of control systems with feedback over communication channels. In contrast to alternative approaches, the proposed framework provides simpler solutions to a restricted but important class of problems while establishing direct links with well-known analysis and design tools in control systems theory.
Sampled-data control systems. Braslavsky and coworkers have developed a frequency domain lifting approach to sampled-data systems, which was instrumental in capturing intersample information to give the first definitive analysis of robustness and sensitivity tradeoffs in these systems. Another significant contribution in this area was the derivation of a new, rigorous proof of the Poisson sampling formula to discretise an analog system.
Nonlinear control systems. Braslavsky and coworkers developed the optimal cheap control approach to first quantitatively characterise design limitations in nonlinear systems and link them to Bode integrals. Dr Braslavsky and coworker also established conditions under which global or semi-global stabilisation is impossible for a class of cascade systems, and has also collaborated in the robustification of bakstepping design and design tradeoffs in nonminimum phase systems.
Optimal filtering. Braslavsky and coworkers developed a filtering version of the cheap control approach to analyse limiting performance of Kalman filters and draw links between Bode integrals and Wiener filtering problems.
Between 2003 and 2010, as part of his work for the ARC Centre for Complex Dynamic Systems and Control (CDSC) at The University of Newcastle, Braslavsky was project leader and later programme leader of CDSC Industry Programme on Process Control and Optimisation, jointly funded by the ARC, BHP Billiton Innovation and Matrikon.
In November 2010 Braslavsky joined CSIRO Energy Technology as a Senior Scientific Researcher, remaining as a Conjoint Senior Lecturer with the University of Newcastle.
