摘要：
This paper investigates the fixed-time consensus tracking problem for second-order multi-agent system with mismatched perturbations in directed topology networks. Based on the fixed-time disturbance observer, the system is estimated to match the disturbance. Secondly, a sine compensation function is introduced to design a nonsingular distribute protocol, the unmatched disturbances were overcome while avoiding the singularity of the system, so that the multi-agent system achieves fixed-time consensus tracking. Finally, simulation is included to demonstrate the performance of the new algorithm. Copyright © 2021 Acta Automatica Sinica. All rights reserved.
