Abstract

Abstract:

In view of the finite time consistency tracking problem for second-order multi-agent systems with channel fading, a distributed control algorithm based on sliding mode strategy is proposed in this study. According to the topology structure of the agent, a mathematical model is built to construct the consistency error function under the influence of random channel fading.The consistency protocol based on error function is designed to transform the consistency problem into the stability problem of tracking error system.In this study, an exponential non-singular terminal sliding mode surface is designed, and the finite-time stability and sliding mode accessibility of the error system are analyzed by combining Lyapunov stability theory and sliding mode control theory.A multi-agent model with one leader and four followers is used to conduct simulation experiments. The results show that four followers can accurately track the leader and achieve the tracking consistency of the system, and the error function curve tends to 0 at 10s, which proves the effectiveness of the control strategy.
