Abstract：For the problems of uncertain parameters and limited system communication ability in general nonlinear multi-agent systems under directed graphs,a consensus control protocol combining model reference adaptation and event-triggered mechanism is proposed.The protocol first designs a reference agent for each uncertain agent,the design of adaptive law ensures the effective estimation of uncertain parameters,then sends the reference agent state to neighbor agents based on an event-triggered mechanism,and finally designs a controller based on the received neighbor reference agent state and its actual state.This protocol adopts the method of designing event trigger strategy based on the reference model of the agent to effectively avoid continuous communication between agents and reduce system communication resources.The matrix theory,algebraic graph theory,and Lyapunov stability theory are used to prove the control strategy.General nonlinear uncertain multi-agent systems can achieve consensus without Zeno behavior.Simulation examples further verify the validity of the theoretical results.
