Abstract: In this paper, for nonlinear multi-agent systems under switching topologies with communication failure, the leader-following consensus problem is studied. Firstly, several switching topologies including a null graph are considered. Secondly, the novel consensus protocols for followers are given considering the communication failure (null graph). Then the convergence analysis is presented and some sufficient conditions are derived for the consensus tracking in a leader-followers multi-agent network. The analysis tools developed in this paper are based on matrix theory and control theory. Finally, the simulations show that by the proposed theorem, the consensus can be achieved and the control gain can influence the speed of the consensus.

Keywords: Multi-agent systems, communication failure, consensus, switching topologies
