Dynamic Event-Triggered Asynchronous Switching Control Approach with Applications to AC-DC Converter

Abstract

This paper addresses the problem of dynamic event-triggered asynchronous switching control approach with applications to AC-DC converter. In practice, switching of controllers is often lagged behind that of their corresponding subsystems owing to signal transmission, system detection and so on. Therefore, in this paper, we adopt asynchronous switching model to describe the system with asynchronous phenomenon. Based on Lyapunov function method and the average dwell time approach, stability criterion is proposed for the resulting closed-loop system in linear matrix inequalities(LMIs). Then, dynamic event-triggered state feedback controller is designed to guarantee the global exponential stability of event-triggered asynchronous switching systems. Finally, a numerical example is exploited on AC-DC converter switched systems to demonstrate the effectiveness of the proposed control framework.
