This paper studies the lag group consensus problem ofthe second-order nonlinear multi-agent systems. A protocol mixedwith the adaptive control approach is presented for agents to behindthe leader in each group at different times, so as to avoidcongestion. Without assuming that the topology is connected orweakly connected even there is rooted directed spanning tree,sufficient conditions for the lag group consensus are proposedanalytically. Moreover, it is shown that with the given protocol, nomatter what topology of the multi-agent system is, the lag groupconsensus can be obtained always. Finally, a simulation example isgiven to illustrate our theoretical analysis. |
