Consistency Analysis And Control Of Networked Multi-Agent System

In the past decade,owing to its wide application prospects,the problem of consistency control of networked multi-agent systems has been attracted great attention in many fields.But the current research conditions for this problem are too ideal,which are far from the actual control system.Therefore,this problem will be further investigated in this paper.The main research contents include the following aspects:Different single continuous event-triggered mechanisms are proposed for first-order systems and general linear systems under different constraints,such as time-delay,uncertain switching topologies.Since networked multi-agent systems generally sample states at a fixed frequency,which will cause the waste of resources.By introducing single continuous event-triggered strategies to reduce the times of controller updates,network resources are saved.Meanwhile,for the two single continuous event-triggered mechanisms,it is proved that any adjacent execution interval has a positive lower bound,so the Zeno behavior that may be brought by the system is excluded.A new consistency method is proposed for general linear multi-agent systems with time-varying delay control inputs and double-ended stochastic cyber-attacks.The mathematical model of the closed-loop control system is established under the time-varying delay control input and the double-ended stochastic cyber-attacks.Based on the Lyapunov stability theory and the LMI theory,the sufficient conditions for ensuring the consistency of the system in the mean square sense are given.Finally,the effectiveness of the theoretical method is verified by simulation example.Aiming at networked multi-agent systems with time-delay and uncertain switching topologies and stochastic cyber-attacks,a hybrid-triggered consistency control protocol was proposed.Compared with the event-triggered mechanism,the hybrid-triggered mechanism can better guarantee the optimal performance of the system.The effects of time-varying delay control input,uncertain switching topologies and stochastic cyber-attacks are also considered,the mathematical model of the closed-loop system is established,based on the Lyapunov stability theory and LMI theory,consistency theorem that makes the system consistent is given.Finally,the feasibility of the theory is verified by simulation example.
