Fixed-time Sliding Mode Consensus Control for Nonlinear Multi-agent Systems with External Disturbances
Yingmei He, Bin Xin, Yixi Yang, Shuai Cheng · 2024
This paper studies the consensus tracking problem of nonlinear multi-agent systems with external disturbances and proposes a new fixed-time sliding mode consensus control method based on disturbance observer. A new fixed-time disturbance observer is constructed, which accelerates the estimation speed of disturbances. Based on the observer, a disturbance resistant fixed-time sliding mode consensus control protocol is designed to help the state tracking errors of the multi-agent systems converge to a small neighborhood of zero within a fixed time. The comparative simulation results demonstrate the effectiveness of the proposed strategy.
