The Consensus Analysis Of Multi-agent System Based On Event Trigger

Agent is an individual who perceives environmental information autonomously in a complex dynamic environment,takes actions autonomously,and could accomplish a series of objectives or missions.A system is consist of multiple agents,which is called a multi-agent system.Multi-agent system has been widely applied in many fields,which is a study hotspot theme in control science.Contrasted with traditional control system,multi-agent system has the superiorities of lessening costing and boosting system productivity.The consensus problem is the fundamental issue of multi-agent system.It is of great significance for multi-agent system to probe into the formation consensus problem,cluster consensus problem and adaptive tracking problem.For the sake of further lessen the squander of energy sources and enhance the properties of the system,this paper considers the consensus of linear continuous system and linear discrete system respectively from the point of view of event triggering.For linear continuous time multi-agent system,which is researching the output feedback control strategy based on event triggering.In this paper,the consensus control law relying on a few discrete points communication is adopted to improve the limitations of continuous monitoring of the agent's own state,and no Zeno phenomenon occurs,which does not need to occupy a large number of data resources.An observer-based consensus controller based on event trigger forecast is put forward,in order to settle the consensus control problem under output feedback.The theoretical results are verified by combining numerical simulation examples.For linear discrete time isomorphic multi-agent systems,considering the inevitability of network delay,this paper presents an output-based predictive control problem for network control systems with communication delay by introducing an event triggering algorithm.First,when the output error meets the given condition,the event trigger will be carried out.The Lyapunov function was structured to testify the stabilization of the closed-loop system.The stability of the Lyapunov theory and algebraic graph theory were applied to validate that the system could ultimately arrive consensus.Finally,under this control strategy and there no generate Zeno behavior.The theoretical results are verified by combining numerical simulation examples.
