研究了一类具有脉冲扰动的复杂网络。研究了网络的预定时间同步问题，其中稳定时间与初始条件和系统参数无关。也就是说，可以根据任务要求预先分配稳定时间。由于准同步控制方法在实际工程中应用广泛，本文还研究了预给定时间准同步问题。基于线性矩阵不等式技术和李雅普诺夫方法，给出了在所设计的事件触发传输策略下，受控系统实现预定时间同步和预定时间准同步的充分判据.芝诺行为被排除在外。最后给出了两个数值例子来验证主要结果的正确性。
In this paper, a class of complex networks with impulsive perturbations is studied. And the problem about pre‐specified time synchronization of networks is considered, in which the settling time is independent of any initial conditions and system parameters. Namely, the settling time can be assigned in advance according to task requirements. Due to that quasi‐synchronous control methods are widely used in practical engineering, the problem about pre‐specified time quasi‐synchronization is also investigated. Based on the linear matrix inequality technique and Lyapunov methods, some sufficient criteria are derived, ensuring pre‐specified time synchronization and pre‐specified time quasi‐synchronization of the controlled systems under the designed event‐triggered transmission strategies. And Zeno behaviors are excluded. Finally, two numerical examples are given to verify the correctness of the main results.
