Abstract
This brief investigates the problem of <i>finite-time robust consensus</i> (FTRC) for second-order nonlinear multiagent systems with external disturbances. Based on the global finite-time stability theory of discontinuous homogeneous systems, a novel finite-time convergent <i>discontinuous disturbed observer</i> (DDO) is proposed for the leader-following multiagent systems. The states of the designed DDO are then used to design the control inputs to achieve the FTRC of nonlinear multiagent systems in the presence of bounded disturbances. The simulation results are provided to validate the effectiveness of these theoretical results.This brief investigates the problem of <i>finite-time robust consensus</i> (FTRC) for second-order nonlinear multiagent systems with external disturbances.
