1 Introduction
Many interesting problems arising from distributed control of multi-agent systems (MAS), such as flocking control, rendezvous control, formation control, containment control’ coverage control, etc., can all be regarded as the extended issues of consensus control. The objective of consensus problem is to design a distributed control input such that the states of a team of agents can reach an agreement by just using local information from the agents' neighbors. Recent years have witnessed an increasing attention towards the consensus problems of MAS due to its wide applications in formation control of unmanned aerial vehicles (DAVs), distributed sensor networks and attitude alignment of satellite clusters [1], [2].
