Output Feedback Periodic Event-Triggered Control of Switched Stochastic Nonlinear Systems and Its Applications

초록

This article is devoted to the problem of periodic event-triggered output feedback stabilization for non-strict feedback switched stochastic nonlinear systems (SSNSs) in the context of average dwell time (ADT) constraints. Specifically, a mode-dependent state observer is constructed to estimate the unmeasured system state. Striving to curtail the waste of communication resources (WCRs) of the considered system, this article builds a periodic event-triggered control (PETC) scheme, which constitutes an event-triggered controller and a discrete-time event-triggering mechanism (ETM). With the proposed scheme, only the information regarding the system output and the system mode at the sampling instant is exploited. To guarantee that the closed-loop system (CLS) is asymptotically stable (AS) in mean square (MS) despite the incidence of asynchronous switching, a novel correlation between the sampling period and the ADT is thus established. Finally, the effectiveness of the proposed scheme is confirmed using two practical examples.
