Resilient Sampled-Data Event-Triggered Control for Switched Systems Under Denial of Service Attacks

Abstract

This paper focuses on the asynchronous event-triggered control problem for networked switched systems with denial-of-service (DoS) attacks. To counteract the negative influence of DoS attacks and permit the system frequent switching to occur within between event-triggered intervals, the resilient event-triggered mechanism (ETM) is established. The delayed switching system model is constructed to describe the sampling period, resilient ETM and DoS attacks. A piecewise Lyapunov functional is established to analyse the exponentially stable of the switched system. Meanwhile, a coordinated design method is given for the controller gains and event-triggered parameters. Finally, the networked continuous stirred tank reactor system is used to verify the feasibility of method.
