Research On Consensus Of Multi-agent System Under Communication Constraint And Packet Loss

As a brand-new decentralized computing technology,the multi-agent system has attracted the attention of many scholars.As an important branch of complex systems,multiagent systems combine basic disciplines such as mathematics and physics,and have been widely used in various fields.This thesis conducts an in-depth study on the consensus of multi-agent systems under communication constraints and packet loss environments.The so-called consensus of a multi-agent system means that certain states of agents tend to be the same under a control law.However,in the actual information transmission,the multi-agent system network is inevitably restricted by the environment.An agent may be affected by multiple external disturbances that affect the information transmission,or the information between parts cannot be transmitted due to the loss of information in the process.For this reason,based on the knowledge of stability theory,matrix analysis and graph theory,this paper designs a suitable control protocol,and studies the consensus of multi-agent systems in a complex network environment more deeply.The specific content is as follows:1.Aiming at the multi-agent system under fixed topology and switching topology,as well as the communication time delay associated with the agent's information transmission,a distributed control protocol with proportional integral is proposed.The proportional integral part of the protocol can reduce the impact of multiple disturbances.In addition,this section conducts theoretical derivation and analysis of the consensus conditions of the system,and derives the consensus conditions of the system.Finally,the simulation verifies its effectiveness.2.For the fractional-order multi-agent system,considering the random packet loss during communication,as well as the genetic and infinite memory characteristics of the fractional-order system,sampling control and the design of a suitable controller are used to convert the problem to an integer-order discrete system.By constructing the V function and combining the linear matrix inequality theory,this paper obtains the conditions for the system to reach consensus,and finally the numerical simulation verifies the validity.Finally,full text is summarized,the future research direction and development trend of the consensus of multi-agent system under complex network environment are prospected.
