In view of the limited communication resources between neighboring nodes in multi-agent systems,this paper studies the adaptive reliable consensus control problem of multi-agent systems based on dynamic event-triggered communication protocol.Firstly,a fault-tolerant control policy based on adaptive parameter estimation technology is designed to address unknown actuator faults.Secondly,a novel dynamic event-triggered function is proposed,which prolongs the event-triggered interval by introducing a dynamic variable with adaptive adjustment capability.On this basis,it has been proved that the proposed method can ensure the convergence of consensus er-ror solely based on the interaction information between the intelligent agent and its neighbors at the triggering time,in the case of discontinuous communication between agents.In addition,this paper theoretically demon-strates that there is no Zeno phenomenon in event-triggered communication between agents.Finally,a simulation of unmanned ship formation system is carried out,and the result can illustrate the effectiveness of the adaptive event-triggered reliable control method proposed in this paper.
