In this paper, we investigated the finite-time
consensus tracking problem for multi-agent systems with external bounded
disturbances and input bounded
disturbances and unknown velocities. Based on the Lyapunov finite-time theorem, a novel finite-time
consensus control is constructed by using the backstepping method. For unknown velocities, the high-gain observer is used to estimate the velocity information. It is proved that the
consensus can be achieved in finite time. The
consensus shows fast response and strong robustness to various
disturbances. Finally, the effectiveness of the results is illustrated by numerical simulations.
