Abstract
This paper is concerned with the event-triggered practical fixed-time containment control for stochastic multi-agent systems, in which the input delay is considered. A novel event-triggered mechanism is proposed, where the containment error of stochastic MASs is considered as a part of the threshold function in the form of an exponential decreasing function, which can provide more freedom to balance system performance and resource utilization. Then, a practical fixed-time containment control scheme is presented, whose convergence time is not affected by the initial conditions. Furthermore, Pade approximation technique is utilized to convert the input delay to the case without delay. The design process of the controller is simplified, and the computational complexity is reduced. Finally, two examples are rendered to demonstrate the performance of the presented method.
