Distributed event-triggered fixed-time consensus for leader-follower multiagent systems with nonlinear dynamics and uncertain disturbances

This paper focuses on the distributed event-triggered fixed-time consensus control problem of leader-follower multiagent systems with nonlinear dynamics and uncertain disturbances. Two distributed fixed-time consensus protocols are proposed based on distributed event-triggered strategies, which can substantially reduce energy consumption and the frequency of the controller updates. It is proved that under the proposed distributed event-triggered consensus tracking control strategies, the Zeno behavior is avoided. Compared with the finite-time consensus tracking, the fixed-time consensus tracking can be achieved within a settling time regardless of the initial conditions. Finally, 2 examples are performed to validate the effectiveness of the distributed event-triggered fixed-time consensus tracking controllers.
