Consensus of switched multi-agent systems based on observers

This paper investigates the consensus problem of multi-agent systems which each agent ia a switched system with a fixed topology. Each subsystem of any agents is not stabilizable, the discretized Laypunov function technique is applied to design switching law satisfying dwell time. Since the states of agents can not be measurable, a distributed observer-based consensus protocol is proposed to solve the consensus problem for switched multi-agent systems. A sufficient condition is obtained to achieve consensus of switched agent networks.
