Abstract

Hybrid dynamical systems have attracted the attention of many researchers in recent years. Such systems are capable of exhibiting simultaneously continuous-time dynamics and discrete-time dynamics, and jump phenomena. They provide a natural framework for mathematical modeling of complex reactive systems in which physical processes interact with man-made automated environments. This talk will discuss some recent results on the stabilization of hybrid dynamical systems. Assuming certain properties of a convex linear combination of the nonlinear vector fields, some stabilizing switching rules are proposed. Stability analysis is performed in terms of two measures so that the results can unify several stability criteria, such as Lyapunov stability, partial stability, orbital stability, and stability of an invariant set.
