Title: “L1 Adaptive Control and Its Transition to Practice“
Speaker:
Dr. Naira Hovakimyan, aff. Prof.
Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign (UIUC)
Professor and Schaller Faculty Scholar
Naira Hovakimyan has a PhD in “Physics and Mathematics” from the Institute of Applied Mathematics of Russian Academy of Sciences, majoring in optimal control and differential games. In the USA, Dr. Hovakimyan worked at Georgia Tech and Virginia Tech before moving to UIUC in 2008. She has co-authored a book and more than 250 refereed publications. Her current interests are in the theory of robust adaptive control and estimation amongst others with an emphasis on aerospace applications.
Abstract:
While the benefits of adaptation in the presence of failures and uncertainties could be shown in various flight tests over the last decades, the major challenge related to stability/robustness assessment of adaptive systems is still being resolved based on testing the closed-loop system for all possible variations of uncertainties in Monte Carlo simulations. This talk will give an overview of the limitations inherent to the conventional adaptive controllers and will introduce the audience to the L1 adaptive control theory, the architectures of which have guaranteed robustness in the presence of fast adaptation. Various applications, including flight tests of a subscale commercial jet, will be discussed during the presentation to demonstrate the tools and the concepts. With its key feature of decoupling adaptation from robustness, L1 adaptive control theory has facilitated new developments in the areas of event-driven adaptation and networked control systems. A brief overview of initial results and potential directions will conclude the presentation.
