Asynchronous Event-Triggered Output Feedback Control for CPS Under Data Injection Attacks

This paper is concerned with the problem of event-triggered dynamic output feedback control for continuous-time cyber-physical systems under data injection attacks. The resulting criterion provide sufficient conditions to ensure the asymptotic stability of the closed-loop system subject to compromising both measurement and control channels. Event-triggered mechanisms are implemented at both sensor and controller nodes asynchronously in order to alleviate the number of control actions against attacks and reduce communication burden. Moreover, we present a co-design procedure to simultaneously synthesize feedback laws and event-triggering parameters. Finally, numerical examples are included to show effectiveness of the proposed method.
