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

ABSTRACT 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.
