Abstract: In this paper, the problem of group consensus for a nonlinear multiagent system with switching topology under DoS(denial of service) attack is studied. A distributed control protocol based on local information is presented and then the consensus of the system is guaranteed in each group under DoS attack. The consistency of the system in a certain DoS attack conditions can be achieved based on the Lyapunov method. It is proved that each agent can be consistent with the leader of its group, under the action of the controller. The case of switching topology of the multiagent system is taken into account as well. Furthermore, the situation of group consensus with time-delay and a special case of DoS attack are also considered as supplements. Finally, two simulation examples are given to verify the effectiveness of the control protocol.
