[Abstract]:In recent years, the consistency of multi-agent systems has become a hot topic in many fields, such as physics, applied mathematics, computer science and control theory. The dynamics of each multi-agent may be different and cluster consistency is common, so, It is of great practical significance to study the group consistency of heterogeneous systems. In this paper, we introduce two clustering coefficients to cluster heterogeneous multi-agents. The main contents and innovations of this paper are as follows: 1. Combining with cluster coefficients, we design the control input of a heterogeneous continuous multi-agent system. Under fixed undirected topology, we construct Lyapunov function reasonably. It is proved that the system can achieve group consistency, and when the feedback coefficient is within a certain range, the system can be transformed from the equation form to the matrix form. The necessary and sufficient condition that the system can achieve group consistency is that the topological graph contains a directed spanning tree and obtains the group uniform convergence point, and the matrix of the system in matrix form is analyzed under switched directed topology. When the feedback coefficient and the period satisfy certain conditions, if there is a continuous bounded and non-overlapping infinite interval sequence, and the joint graph of the topological graph set in each time interval series is switched to contain the directed spanning tree, we obtain the following results: (1) when the feedback coefficient and the period satisfy certain conditions, if there is a continuous bounded and nonoverlapping infinite interval sequence, The system achieves group consistency. 2. The group consistency of heterogeneous discrete systems is studied. Under fixed undirected topology, by reasonably constructing a Lyapunov function, it is shown that when there is a positive definite matrix satisfying certain conditions, the system can achieve group consistency. Under the fixed directed topology, the random matrix transformed from the system model is analyzed, and it is proved that when the feedback coefficient is within a certain range, the system achieves group consistency when the topological graph contains a directed spanning tree. The random matrix is analyzed. When the feedback coefficient and period are in a certain range, if there is a continuous bounded and nonoverlapping infinite interval sequence, When the joint graph of switching topological graph set contains directed spanning tree in each interval sequence, the system achieves group consistency. 3. The group consistency of heterogeneous continuous system with periodic intermittent control under fixed undirected topology is studied. On the basis of continuous system control input, a batch control is applied to some multi-agents. By constructing a reasonable Lyapunov function, it is obtained that when s 鈮，
