Fixed-Time Consensus Control for Second-Order Multi-Agent Systems: An Improved Dynamic Event-Triggered Approach

This paper develops a fixed-time consensus(FTC) control approach under dynamic event-triggered scheme(DETS) to deal with the consensus problem of second-order nonlinear multi-agent systems(SONMAS). First, a new DETS which can result in larger internal variable to reduce the frequency of event-triggered is designed to save communication and chip resources and Zeno behavior can be avoided. Second, a FTC approach is proposed by adding a novel item which can enable the MAS reach consensus quickly. Fixed-time convergence is proved based on Lyapunov theory which can obtain the more conservative settling-time which can reflect the consensus time well. At last, the effectiveness and feasible of the proposed DETS and controller is verified.
