Adaptive Fuzzy Secured Control for Multiagent Systems Under DoS Attacks and Intermittent Actuator Failures

In this article, the security-based adaptive fuzzy control issue is studied for strict feedback multiagent systems with actuator failures and denial-of-service (DoS) attacks. Fuzzy logic systems (FLSs) are applied to approximate unknown nonlinear functions. In order to deal with the discontinuous signals caused by DoS attacks, a distributed filter is constructed. Based on the proposed filter and the backstepping control technique, a security-based robust adaptive fuzzy fault-tolerant controller is designed to compensate for the effect caused by intermittent actuator faults. The proposed control method can ensure the tracking error converges to a small neighborhood of the origin and all signals in the closed-loop system are bounded. Finally, simulation results are given to demonstrate the effectiveness of the proposed control method.
