Abstract
In this article, we study the adaptive fault-tolerant control (FTC) for multiagent systems (MASs) under denial-of-service (DoS) attacks and actuator faults. The mixed connectivity-maintained/broken attack containing both connectivity-maintained and connectivity-broken attacks is considered, which results that the MASs are with switching topologies. Also, characteristics of DoS attacks, such as durations and frequencies of attacks, make it more difficult to design fault-tolerant controllers and analyze the stability for MASs with node faults. A novel FTC strategy is presented to compensate for node faults. Then, by using the Lyapunov stability analysis, an average dwell-time condition is presented for the bounded synchronization of MASs under DoS attacks. An example of nonlinear forced pendulum systems is proposed to verify the proposed approach.
