摘要

In this paper, the distributed consensus and tracking protocols are developed for the second-order time-varying nonlinear multi-agent systems under general directed graph. Firstly, the consensus and tracking problems can be converted into a conventional stabilization control problem. Then a state transformation is employed to deal with the time-varying nonlinearities. By choosing an appropriate time-varying parameter and coupling strengths, exponential consensus and tracking of second-order nonlinear multi-agent systems can be achieved. Finally, a simulation is given to illustrate the effectiveness of the proposed consensus and tracking protocols.
