This paper is concerned with the nonchattering fixed-time consensus of multi-agent systems. Based on the theory of Lyapunov stability, sufficient conditions are derived for achieving consensus within the fixed time, where the estimation of upper bounded time is independent on the initial states. Furthermore, distinguished from the traditional signum contained in finite- and fixed-time control protocol, the proposed novel control scheme is nonchaterring, which is benefit to the performance of multi-agent systems. Finally, a numerical example is used to validate the effectiveness and feasibility of the theoretical results.

Key words: multi-agent, consensus, fixed-time, nonchattering
