Abstract: Reinforcement learning(RL) methods and fully distributed event driven control strategies are used to study the bipartite consensus problem of multi-agent systems(MASs) with unknown system model information.Firstly,a hybrid event triggered mechanism based on state threshold and time threshold is proposed to reduce the communication frequency between intelligent agents.Secondly,an adaptive event triggered consensus control protocol is designed using locally sampled state information,resulting in the consensus error of all following agents eventually approaching zero.The effectiveness of the above event triggered mechanism is confirmed by excluding Zeno behavior within a limited time.Then,based on the RL method,a model free algorithm is proposed to obtain the feedback gain matrix,and an adaptive event triggered control strategy is constructed in the presence of unknown model information.Unlike existing related works,the RL-based event triggered adaptive control algorithm only relies on locally sampled state information and is independent of any model information or global network information.In addition,we extend the above results to the switching topology scenario,which is more challenging because the state estimation is updated in the following two situations:1)when the interaction graph switches or 2)when the event triggering mechanism is satisfied.Finally,the effectiveness of the adaptive event triggered control algorithm is verified through examples.
