    In this paper, the cluster consensus problem of linearly coupled multi-agent systems in directed networks is studied by constructing a Laplacian of a directed graph. Different from the former work in which the clusters are divided artificially, in this paper, the relationship between the number of the clusters and the Laplacian is revealed. It is obtained that the number of clusters equals to the ... View full abstract»
