摘　　要：针对信道带宽受限的无线网络控制系统(NCSs),提出了包含事件触发机制、信号量化和状态反馈L2控制的协同设计方法。首先,针对无线网络时变延时,提出一种事件触发机制,并建立了线性系统的量化控制数学模型。其次,基于该模型,并利用李亚普若夫泛函和线性矩阵不等式方法,证明了系统时滞独立的L2量化控制的稳定性,并给出了求解事件触发器参数和L2量化控制的协同设计方法。最后,通过仿真验证了所提方法的有效性。In view of the limited channel bandwidth of wireless network control systems （NCSs）, a co-design method of event-triggered scheme, signal quantization and state feedback L2 control are proposed. Initially, in consideration of wireless network time-varying delay, an event-triggered communication scheme is put forward, and the mathematical model of quantization control for linear systems is established. Furthermore, based on this model and by applying a new Lyapunov function and linear matrix inequality method, criterion for the delay-dependent L2 quantization stabilization and criterion for the co-design of both the state feedback gain and the trigger parameters are derived. Finally, the effectiveness of the proposed method is verified by simulation.
