To address the issue of poor system adaptability inherent in traditional event-triggered mechanisms,a problem of dynamic event-triggered consensus of uncertain multi-agent systems under switching topology was studied. The event-triggered mechanism could not effectively guarantee the system adaptability in practice. It was proposed to use the dynamic event-triggered mechanism to dynamically adjust the current state of the system, which could reduce the frequency of the system update. In designing the consensus controller, factors such as switching topology, time delays, and external disturbances were considered. Algebraic graph theory and related theoretical methods proved that the dynamic event-triggered mechanism set the consensus controller to achieve the consensus of the uncertain multi-agent system. Finally, the simulation results confirmed that the method is reasonable.
