Abstract
In this paper, we study the consensus tracking problem for high-order nonlinear uncertain multiagent systems. By using the fixed-time control technique and the modified addition of a power integrator method, a novel distributed observer-based consensus protocol is proposed. Compared with the existing results in the literature, the proposed protocol can achieve consensus tracking in a fixed time independent of initial conditions even in the presence of unknown parameters and nonlinear uncertainties bounded by positive functions. Simulation examples are given to illustrate the effectiveness of the theoretical results.Keywords
