The consistency of uncertain multi-agent systems based on dynamic event triggering mechanism under network attacks is studied.Traditional event triggering mechanisms cannot effectively save network resources by changing the triggering rules.Dynamic event-triggering mechanism is introduced.On the basis of the dynamic variables of the mechanism,the event triggering conditions are dynamically adjusted according to the running state of the system,so as to reduce the frequency of control updates.The mathematical model of the closed-loop control system is established under the delay control input,network attacks and the trigger of dynamic events.The consistency of multi-agent systems under dynamic event triggering control is proved by Lyapunov stability theory and Linear Matrix Inequality (LMI) theory.Finally,the effectiveness of the proposed method is verified by simulation experiments.
