Information consensus for multi-agent systems via nonlinear protocols

In multi-agent system, the communication topology of agent network plays a very important role in its consensus problem. In this paper, we consider a new consensus nonlinear protocol for networks of dynamic agents that allow the agents to agree in a distributed and cooperative fashion. We consider the network with external disturbance. We use a Lyapunov approach to prove that the asymptotical consensus can be reached. Finally, we perform a simulation study to verify the efficiency of the proposed scheme.
