This paper addresses the secure quasi-synchronization issue of heterogeneous complex networks (HCNs) under aperiodic denial-of-service (DoS) attacks with dynamic event-triggered impulsive scheme (ETIS). The heterogeneity of networks and the aperiodic DoS attacks, which hinder communication channels and synchronization goals, present challenges to the analysis of secure quasi-synchronization. The ETIS leverages impulsive control and dynamic event-triggered scheme (ETS) to handle the network heterogeneity and the DoS attacks. We give specific bounds on the attack duration and frequency that the network can endure, and obtain synchronization criteria that relate to event parameters, attack duration, attack frequency, and impulsive gain by the variation of parameter formula and recursive methods. Moreover, we prove that the dynamic ETS significantly reduces the controller updates, saves energy without sacrificing the system decay rate, and prevents the Zeno phenomenon. Finally, we validate our control scheme with a numerical example.
本文研究了在具有动态事件触发脉冲方案（ETIS）的非周期性拒绝服务（DoS）攻击下，异构复杂网络（HCNs）的安全准同步问题。网络的异构性和非周期性DoS攻击会阻碍通信通道并影响同步目标，给安全准同步分析带来了挑战。ETIS利用脉冲控制和动态事件触发方案（ETS）来处理网络异构性和DoS攻击。我们给出了网络能够承受的攻击持续时间和频率的具体界限，并通过参数变化公式和递归方法得到了与事件参数、攻击持续时间、攻击频率和脉冲增益相关的同步准则。此外，我们证明了动态ETS显著减少了控制器更新，在不牺牲系统衰减率的情况下节省了能量，并防止了芝诺现象。最后，我们通过一个数值例子验证了我们的控制方案。
