Output feedback stabilization of invariant sets for switched systems
切换系统不变集的输出反馈镇定

By employing a nonnegative function V (x), we extend the definitions of small-time and large-time state-norm observability to the definitions of small-time and large-time V (x) observability. Based on the concept of V (x) observability, we stabilize the invariant sets of the switched systems with passive subsystems by using the bounded output feedback and the dynamic output feedback. The results are proved in detail by using multiple Lyapunov functions. Numerical examples are employed to verify the proposed method.
