摘要

In this paper, a finite-time consensus protocol for multi-agent networks is discussed from a new perspective. The order beta of the nonlinear function in the protocol is shown to be a crucial parameter in analyzing the finite-time consensus property of multi-agent networks with a detail-balanced communication topology. When beta > 0, the corresponding protocol can guarantee the consensus of the multi-agent networks. In particular, if beta is an element of (0, 1), the consensus can be realized within finite time. A leader-follow model is also investigated in this paper. Finally, several concrete protocols are proposed based on our theoretical analysis, and numerical examples are given to make a comparison among different protocols from the aspect of convergence speed.
