Adaptive Resilient Event-Triggered Control for Networked Switched Systems Under DoS Attacks

This paper is concerned with the adaptive resilient event-triggered control problem for networked switched systems with nonperiodic denial of service (DoS) attacks. In order to save limited network bandwidth and reduce the negative impact on system performance caused by DoS attacks, a novel adaptive resilient event-triggered scheme (ARETS) is developed, which can save the communication cost and improve the flexibility of the system. With considering the ARETS, dwell time switching and transmission delays, the criterion of asymptotic stability and ${\mathcal{L}_2}$-gain performance is derived such that the system under DoS attacks owns security performance. On this basis, the co-design conditions of the ARETS and the controller are proposed. Finally, a simulation example is given to verify the effectiveness and merits of the proposed method.
