Practical Fixed-time Distributed Average-tracking with Input Delay Based on Event-triggered Method
This paper addresses the distributed average-tracking (DAT) problem of multiagent networks (MANs) with same input delay under an undirected topology. A distributed fixed-time average-tracking algorithm driven by an event-triggered method is constructed to ensure the agents reach the average value of multiple time-varying reference input signals (TVRISs) within the fixed time. By using Lyapunov function method, sufficient conditions on estimating the fixed settling time and the bounded average-tracking errors are obtained. In addition, it is proved that the event-triggered control strategy avoids the Zeno behavior. Finally, a few numerical simulations are given to illustrate the effectiveness of the proposed algorithm.
Keywords Distributed average-tracking, event-triggered method, fixed-time control, input delay, multiagent networks.

Abstract
This paper addresses the distributed average-tracking (DAT) problem of multiagent networks (MANs) with same input delay under an undirected topology. A distributed fixed-time average-tracking algorithm driven by an event-triggered method is constructed to ensure the agents reach the average value of multiple time-varying reference input signals (TVRISs) within the fixed time. By using Lyapunov function method, sufficient conditions on estimating the fixed settling time and the bounded average-tracking errors are obtained. In addition, it is proved that the event-triggered control strategy avoids the Zeno behavior. Finally, a few numerical simulations are given to illustrate the effectiveness of the proposed algorithm.
Keywords: Distributed average-tracking, event-triggered method, fixed-time control, input delay, multiagent networks.
