Adaptive fixed-time consensus for stochastic multi-agent systems with uncertain actuator faults

In this paper, we study the adaptive fixed-time consensus control for stochastic multi-agent systems (SMASs) with uncertain actuator faults. Firstly, a fully distributed adaptive consensus protocol and an adaptive fault-tolerant consensus protocol are proposed, respectively, to ensure that the fixed-time consensus of SMASs with actuator faults can be reached. Secondly, an adaptive fault-tolerant containment consensus protocol is further proposed for the SMASs by leveraging the signum function, and this protocol can effectively solve the containment consensus in the unbalanced communication network. Finally, some simulation examples are given to verify the effectiveness of our consensus protocols.& COPY; 2023 ISA. Published by Elsevier Ltd. All rights reserved.

Automated summary

In this paper, the authors study the adaptive fixed-time consensus control for stochastic multi-agent systems (SMASs) with uncertain actuator faults. They propose fully distributed adaptive consensus protocols and an adaptive fault-tolerant containment consensus protocol to achieve fixed-time consensus and solve the containment consensus in unbalanced communication networks. Simulation examples are provided to demonstrate the effectiveness of the proposed protocols.
