Resilient Event-triggered Control for Switched Linear Systems With Network Attacks

This paper studies resilient event-triggered H

control for switched linear systems under periodic denial of service (DoS) attacks. The resilient event-triggering strategy is used to suppress the influence of DoS attacks and increase the utilization of system resources. Instead of using piecewise functions, a united expression is developed to incorporate different system structures inducing by DoS attacks into one form. Then, by the piecewise Lyapunov functional and average dwell time method, sufficient conditions are derived for guaranteeing the global exponential stability with an H

state feedback controllers in terms of linear matrix inequalities (LMIs). At last, a numerical simulation is provided to demonstrate the feasibility of proposed results.
