Relaxed Event-Triggered Control of Networked Control Systems Under Denial of Service Attacks

This paper is concerned with the security analysis and event-triggered control problem of the networked control system (NCSs) subject to denial of service (DoS) attacks. By considering the malicious DoS attacks and partial information via measured outputs, firstly, a relaxed triggering strategy is designed for the NCSs under DoS attacks. Then, the performance analysis and controller design are conducted by Lyapunov-krasovskii method and LMIs technique based on the proposed relaxed triggering strategy. At last, some simulation results show that the proposed relaxed triggering strategy is resilient to DoS attacks with some performance lost.
