Title:
In this paper, a stabilized-region regulator method is presented to solve the output synchronization problem for discrete-time multi-agent systems. The topology structure for the information communication of the agents contains a spanning tree. The innovation of our result is that a stabilized region is designed for discrete-time multi-agent systems and the synchronization problem could be solved by choosing the appropriate parameters. A distributed dynamic feedback control law is designed such that the distribution of the eigenvalues of Laplacian matrix could be regulated into the specified region, then some sufficient conditions used to guarantee output synchronization are presented. At last, the result is extended to the uncertain multi-agent systems. Finally, a numerical, simulation is given to demonstrate the correctness of obtained results. (C) 2015 Elsevier B.V.
