Abstract：A new dynamic event-triggered practical fixed-time average consensus control method is proposed for the nonlinear multi-agent systems with disturbances under switching topologies,and the proposed method converges faster with fewer trigger times.By designing auxiliary dynamic variables and corresponding dynamic equations,a new dynamic event-triggered mechanism is established based on the power terms of dynamic variables,which can reduce event trigger times.Using the designed common Lyapunov function,it is proved that the proposed method is able to guarantee that the multi-agent system can achieve practical fixed-time average consensus under switching topologies,and the upper bound of the convergence time can be set by adjusting the control parameters and is independent of the initial state of the system.By designing the measurement error involving the hyperbolic tangent function,it is proved that there is no Zeno behavior under the proposed method.Finally,some simulation results are provided to illustrate the effectiveness of the proposed control method.
