PRACTICAL ADAPTIVE CONTROL

Distinguished Lecturer, IEEE Control System Society
director of the Active-Adaptive Control Laboratory at
Massachusetts Institute of Technology
Adaptive Control is viewed as a game changer in many application domains where real-time feedback control is essential to ensure the desired performance. Adaptive controllers, whose distinguishing feature is a parameter estimator that prescribes the rule for changing the control parameters in real-time, have been studied extensively over the past forty years, with fundamental properties of stability and robustness well understood. Guidelines for analysis and synthesis for adaptive controllers have been laid out for linear and (specific classes of) nonlinear systems, continuous and discrete-time systems, single-input and multi-input systems, and deterministic and stochastic systems. So what’s missing? There are glaring gaps in adaptive control theory that remain to be closed for adaptive control to be a viable, practical, and easily implementable methodology. Guarantees have to be provided that ensure robustness to a wide variety of non-parametric perturbations. Guidelines have to be in place for a systematic design of all free parameters in the controller. Bounds have to be derived, not only for steady-state behavior, but also for transient characteristics. Implementation issues will have to be satisfactorily addressed. The ability to accommodate actuator constraints in terms of bandwidth, magnitude limits, and rate limits has to be precisely characterized. Recently, there have been breakthroughs in Adaptive Control that have led to reducing the above gaps. This talk will outline the basic principles of the now classical adaptive control theory, but also highlight these recent results and show how they contribute towards making adaptive control practical.

PRACTICAL ADAPTIVE CONTROL
Biography:
Anuradha Annaswamy received the Ph.D. degree in Electrical Engineering from Yale University in 1985. She is the director of the Active-Adaptive Control Laboratory and a Senior Research Scientist in the Department of Mechanical Engineering at MIT. Her research interests pertain to adaptive control theory and applications to aerospace and automotive control, active control of noise in thermo-fluid systems, control of autonomous systems, co-design of control and platform architectures in cyber physical systems, and decision and control in smart grids, smart cities, and critical infrastructures. Dr. Annaswamy has received several awards including the George Axelby and Control Systems Magazine best paper awards from the IEEE Control Systems Society (CSS), the Presidential Young Investigator award from NSF, the Hans Fisher Senior Fellowship from the Institute for Advanced Study at the Technische Universität München in 2008, the Donald Groen Julius Prize for 2008 from the Institute of Mechanical Engineers, and the Distinguished Member award from the IEEE CSS in 2016. Dr. Annaswamy is a Fellow of the IEEE and IFAC. She was an elected member of the CSS Board of Governors from 2010 – 2012; Program Chair of the 2003 American Control Conference (ACC); General Chair of the 2008 ACC; and Program Chair for the 2nd Virtual Control Conference on Smart Grid Technology. She served as the Vice-President for Conference Activities in the IEEE CSS Executive Committee for 2014-15, and will serve as the VP for Technical Activities, CSS Excomm for 2017-18.
