Abstract
Distributed coordination of multi-agent systems has attracted a great deal of attention in the last decades which has found broad applications in sensor networks, robotic teams, and so on. One typical scenario in the coordination of a multi-agent system is to reach a consensus on their states of the agents. In different contexts, two consensus problems are often concerned: the leaderless and leader-following consensus problems. In the leaderless consensus problem, the aim is designing a distributed controller using only local information to drive all the agents reaching a common state, while in the leader following consensus problem, the common state comes from a specific agent called the leader. The local information available to each agent is determined by the interaction network topology among the agents that can be fixed or switching. This talk focuses on the consensus of multiagent systems with switching topologies. In fact, the switching topology induces a switching controller and hence results in the switched closed-loop system. Two consensus problems are revisited and solved based on a novel Krasovskii–LaSalle theorem in switched systems. Possible extensions and some related topics are also discussed.
