Abstract
The impulsive consensus problems of nonlinear time-delay multiagent system under communication constraints are analyzed and investigated in this article. In view of the limited communication channel, global input saturation constraint is integrated into the design of impulse control protocol. Furthermore, in order to reduce energy consumption and communication cost, two kinds of impulsive control protocols are designed that conclude general impulsive control protocols and event-triggered impulsive control protocols. For event-triggered impulsive control protocols, by setting event decision time at impulse time, this novel consensus control protocols not only decrease communication frequency and energy consumption but also avoid “Zeno behavior.” Through theoretical derivation, some sufficient conditions that guarantee the leader-following consensus of multiagent system are presented. In the end, for the sake of explaining the superiority of impulse control combined with event-triggered control strategy in more detail, the simulations of two control methods are given, respectively, for the same multiagent system, which can be better compared and explained.
