Constructive Feedback Control Design for Hybrid Systems

Speaker: Ricardo G. Sanfelice
Affiliation: University of California, Santa Cruz

Abstract: A mathematical framework to model hybrid dynamical systems with inputs and outputs will be presented. Motivated by control design challenges in robotics, power system applications, networked systems, and other cyber-physical systems, tools for the design of feedback controllers will be introduced. The focus will be on tools guaranteeing asymptotic stability of the hybrid closed-loop system with robustness to a general class of perturbations. In particular, relaxed Lyapunov sufficient conditions for stability and attractivity, as well as control Lyapunov functions (CLFs) for the design of feedback laws will be presented. It will be shown that the proposed CLF-based feedback law provides an estimate of the upper value function of the zero-sum hybrid dynamical game, where one player assigns the control and another the disturbance. The tools will be exercised in applications.
