Abstract :  Multi-agent system consists of multiple agents connected by communication  networks. Network is an important factor in analysis and design of multi-agent  systems. In this talk we shall discuss the joint effects of agent dynamic,  network topology and communication data rate on the consensusability of linear  discrete-time multi-agent systems. Neglecting the finite data rate constraint, a  necessary and sufficient condition for consensusability under a set of  distributed control protocols is given which explicitly reveals how the  intrinsic entropy rate of the agent dynamic and the communication  graph affect  consensusability. The convergence rate to consensus is investigated. Moreover, a  necessary and sufficient condition for multi-agent formationability is obtained.  Our results characterize the effects of undirected graphs on  consensability/formationability and optimal convergence rate by the ratio of the  second smallest and the largest eigenvalues of the graph Laplacian matrix. The  implementation of the algorithm on a multi-robot system will be  demonstrated.
