New Result on Event-Triggered Dynamic Output Feedback Control for Discrete-Time Switched Systems

Abstract

In this paper, the event-triggered dynamic output feedback controller for discrete-time switched linear system is addressed. The switching of subsystems during the inter-event interval has always been the focus of researchers’ discussions. Particularly, multiple switching is allowed to happen during an inter-event interval in this paper. To reflect the characteristics of multiple switching during an inter-event interval, the average dwell time approach is adopted in stability analysis. Since the full information of system states can not always be acquired directly, the dynamic output feedback control is taken into consideration. Furthermore, by utilizing a controller-mode-dependent Lyapunov function, we obtain criteria of global exponential stability for switched systems, which are the basis of controller design. At last, we provide a numerical example to prove the validity of the theorem proposed in this paper.
