Fixed-time integral sliding consensus control for multi-agent systems

This paper investigates the fixed-time consensus control issue for multi-agent systems with disturbances. First, an integral sliding mode is developed based on the super-twisting algorithm, which can eliminate the disturbances in a fixed time. A novel fixed-time consensus control algorithm is then proposed with the help of integral sliding mode. Moreover, when the state information is not available, the fixed-time observer and the tracking controller are constructed to achieve the convergence of multi-agent systems, where the observer is proposed based on integral sliding mode. The fixed-time convergence analysis of multi-agent systems with disturbances is given through the Lyapunov stability analysis. Finally, some numerical simulations are shown to certify the effectiveness of the proposed consensus control algorithms. © 2024 South China University of Technology. All rights reserved.
