研究了具有时变时滞的离散复杂网络的指数同步问题。基于Lyapunov函数方法和Razumikhin技术，给出了脉冲离散复杂网络指数同步的几个判据。利用“平均脉冲间隔”的概念，证明了所得结果对于处理同步脉冲和去同步脉冲是有效的。最后给出了几个数值仿真算例，验证了该方法的有效性。仿真结果表明，考虑脉冲间隔的上下限时，该判据的保守性比现有结果要小。
In this paper, the exponential synchronization of discrete-time complex networks with time-varying delay is investigated. Based on the Lyapunov function method and the Razumikhin technique, several synchronization criteria are derived for exponential synchronization of impulsive discrete-time complex networks. Using the concept of ”average impulsive interval”, the derived results are proved to be effective in dealing with synchronizing and desynchronizing impulses, respectively. Several numerical simulation examples are provided to demonstrate the effectiveness of the proposed approach. Moreover, the simulation results show that the criteria are less conservative than the existing results considering the upper or lower of impulsive intervals.
