Event-triggered Control for Switched Linear Systems Under Dual-terminal Cyber Attacks

In this paper, the stability of switched linear systems under dual-terminal data injection cyber attacks is studied. The proposed event-triggering strategy can only sample and update the system state when a defined error exceeds a given threshold. Dual-terminal injection attacks and attack delays are considered. Then, the corresponding closed-loop system is derived. By utilizing Lyapunov functional method and average dwell time technique, stability conditions for the closed-loop system under the event-triggering strategy and dual-terminal injection attacks are given. Accordingly, the design conditions of state-feedback controllers are presented. Finally, simulations are provided to verify the validity.
