Abstract

In this paper, the formation control of multi-agent systems in random switching communication topology is studied, and the problem of excessive bandwidth and low control efficiency among multi-agents is solved. For nonlinear multi-agent systems, a sliding mode formation control algorithm with event-triggered random switching communication topology is proposed. Firstly, a fault-tolerant control strategy based on stochastic system model is designed to solve the problem of low controller efficiency and controller failure during the formation of multi-agent systems. Compared with the traditional multi-agent system dynamic model, the stochastic system model has stronger universality, which improves the efficiency of the controller. Secondly, in order to deal with the problem of high communication load and frequency between agents during formation in random switching communication topology, the sample-based event triggering controller is introduced into the controller, which effectively reduces the communication frequency and reduces the impact of communication delay. Finally, the stability and robustness of event-triggered random switching topology formation control are verified by computer simulation.
