Distributed discrete-time coordinated tracking with Markovian switching topologies

This paper dealswith the distributed discrete-time coordinated tracking problem formulti-agent systems with Markovian switching topologies. In the multi-agent team, only some of the agents can obtain the leader’s state directly. The leader’s state considered is time varying. We present necessary and sufficient conditions for boundedness of the tracking error system and show the ultimate bound of the tracking errors. A linear matrix inequality approach is developed to determine the allowable sampling period and the feasible control gain. A simulation example is given to illustrate the effectiveness of the results. © 2012 Elsevier B.V. All rights reserved.
