研究了一类离散时滞复杂动态网络在动态事件触发机制下的同步控制问题。为了提高能量利用效率，我们首次尝试将动态事件触发策略引入到复杂动态网络的同步控制器设计中。根据控制输入更新之间的绝对误差，提出了一种新的离散时间动态事件触发机制。通过构造适当的Lyapunov泛函，结合引入的事件触发机制，首先分析了每个网络节点的动态特性，然后给出了同步误差动态特性指数终值有界的充分条件。随后，通过求解一个矩阵不等式，设计了一组期望的同步控制器。最后，通过仿真实例验证了所提出的动态事件触发同步控制方案的有效性。
This paper is concerned with the synchronization control problem for a class of discrete time-delay complex dynamical networks under a dynamic event-triggered mechanism. For the efficiency of energy utilization, we make the first attempt to introduce a dynamic event-triggering strategy into the design of synchronization controllers for complex dynamical networks. A new discrete-time version of the dynamic event-triggering mechanism is proposed in terms of the absolute errors between control input updates. By constructing an appropriate Lyapunov functional, the dynamics of each network node combined with the introduced event-triggering mechanism are first analyzed, and a sufficient condition is then provided under which the synchronization error dynamics is exponentially ultimately bounded. Subsequently, a set of the desired synchronization controllers is designed by solving a matrix inequality. Finally, a simulation example is provided to verify the effectiveness of the proposed dynamic event-triggered synchronization control scheme.
