Abstract

To address the fixed-time consensus tracking problem in second-order leader-following multi-agent systems with unknown external disturbances, a fixed-time sliding mode consensus tracking control strategy is designed based on event-triggered mechanisms. First, a distributed fixed-time observer and a fixed-time extended state observer are constructed to accurately estimate the leader’s state and the unknown external disturbances, respectively. Then, based on the observers information, a distributed sliding mode controller is designed to ensure that the tracking errors converge within a fixed time. To enhance communication resource utilization and avoid continuous communication and monitoring among agents, both static and dynamic event-triggered mechanisms are introduced. Finally, a numerical simulation and a practical simulation are conducted to verify the effectiveness and superiority of the proposed control method.
