Based on a distributed state observer, the problem of output feedback synchronisation control for a class of discrete-time delayed complex dynamical networks is studied. In order to solve the energy consumption and communication constraints, dynamic event-triggered mechanisms on sensor and controller sides are proposed by introducing two internal dynamical variables, respectively. Compared with traditional static event-triggered schemes, it effectively reduces the frequency of controller and observer update. Meanwhile, the effects of quantisation occurring in both input and output channels are considered. By means of the linear matrix inequality approach, the distributed state observer and output feedback controller of delayed complex dynamical networks can be designed simultaneously. The exponentially ultimately boundedness of synchronisation errors and estimation errors of complex dynamical networks is guaranteed via the Lyapunov stability theory. Finally, the circuit realisations for the proposed dynamic event-triggered synchronisation control approach are given, and the effectiveness of the obtained theoretical results is demonstrated through the simulation.

具有双通道动态事件触发方案和量化的延迟复杂动态网络的基于观察者的输出反馈同步控制

基于分布式状态观测器，研究了一类离散时滞复杂动力网络的输出反馈同步控制问题。为了解决能耗和通信约束，分别引入两个内部动态变量，提出了传感器端和控制器端的动态事件触发机制。与传统的静态事件触发方案相比，有效降低了控制器和观察器更新的频率。同时，考虑了在输入和输出通道中发生的量化的影响。利用线性矩阵不等式方法，可以同时设计时滞复杂动态网络的分布式状态观测器和输出反馈控制器。复杂动态网络的同步误差和估计误差的指数最终有界性通过李雅普诺夫稳定性理论得到保证。最后，给出了所提出的动态事件触发同步控制方法的电路实现，并通过仿真证明了所获得理论结果的有效性。
