[0057] An optimization method for the consensus problem of multi-agent systems based on subgraph processing, including the following steps:
[0058] 1) Construct the graph signal model of the multi-agent system: according to the communication situation among the agents in the multi-agent system, the topological structure of the graph signal model is drawn, and the observation data of the agent is used as the node signal in the graph signal model, and the multi-agent system is established. The graph signal model of the agent system G=(V,E,A), where V={1,2,…,N} represents the set of nodes; E={e ij} represents the set of edges, e ij =(i,j) indicates that there is an edge connecting node i and node j, A indicates the adjacency matrix of the whole graph, and the adjacency matrix A={a ij}∈R N×N , when there is an edge between nodes i and j a ij =a ji =1, define the degree matrix D of the graph D=diag(d i ),in The Laplacian matrix of a graph is defined as formula (1):
