Stabilization analysis of actuator saturated switched systems with time-varying delays under observer-based event-triggered sampling control

摘要

This paper investigates the stabilization of coupling event-triggered sampling mechanism and observer-based input feedback control of a class of actuator saturated switched systems with time-varying delays. We aim at proposing an event-triggered sampling mechanism based on error norm and state norm. We first develop a sufficient condition for exponentially stable of the dynamic error system constructed by switched systems and observer. By further combining the Lyapunov function method with the convex hull technique, sufficient conditions in terms of LMIs are presented to guarantee the exponential stability of the closed-loop system subject to an average dwell time constraint. Moreover, we verify that the proposed method does not cause Zeno behavior. Finally, with the application to the proposed control of a practical example of two-stage chemical reactor system, the validity and applicability of the conclusion are verified.
