The time-triggered impulsive control of complex homogeneous dynamical networks has received wide attention due to its occasional occupation of the communication channels. This article is devoted to quasisynchronization of heterogeneous dynamical networks via event-triggered impulsive controls with less channel occupation. Two kinds of triggered mechanisms, that is, the centralized event-triggered mechanism in which the control is updated based upon the state information of all nodes, and the distributed event-triggered mechanism where the control is updated according to the state information of each node and its neighboring node, are proposed, respectively, such that the synchronization error between the heterogeneous dynamical networks and a virtual target is not more than a nonzero bound. What is more, the Zeno behavior is shown to be excluded. It is found that the combination method of the event-triggered control and the impulsive control, that is, the distributed event-triggered impulsive control has the advantage of low-energy consumption and takes up many fewer communication channels over the time-triggered impulsive control. Two numerical examples are conducted to illustrate the effectiveness of the proposed event-triggered impulsive controls.
复杂齐次动态网络的时间触发脉冲控制因其偶尔占用通信信道而受到广泛关注。本文致力于通过占用信道较少的事件触发脉冲控制实现异构动态网络的准同步。分别提出了两种触发机制，即基于所有节点的状态信息更新控制的集中式事件触发机制，以及根据每个节点及其相邻节点的状态信息更新控制的分布式事件触发机制，使得异构动态网络与虚拟目标之间的同步误差不超过一个非零界限。此外，还证明了芝诺行为被排除。研究发现，事件触发控制和脉冲控制的组合方法，即分布式事件触发脉冲控制，具有低能耗的优点，并且与时间触发脉冲控制相比占用的通信信道要少得多。通过两个数值例子说明了所提出的事件触发脉冲控制的有效性。
