| 摘 要： | 针对一类存在噪声干扰的时变时延网络化控制系统，基于信息调度与控制协同设计的思想，建立了具有信息调度和噪声干扰的时变时延网络化控制系统模型．引入增广状态矩阵分析方法，研究了存在时变时延和噪声干扰情形下闭环网络化控制系统的鲁棒稳定性问题．给出了使闭环系统渐近稳定的控制器参数化表达式．仿真分析表明该策略在满足闭环系统稳定性的同时，降低了系统信道的数据信息流量，充分地利用了网络带宽资源。

| Abstract: | A kind of networked control system(NCS) with time-varying delays and noise disturbance was studied.A NCS with time-varying delays and noise disturbance is modeled based on information scheduling and control co-design.The robust stabilization of NCS with time-varying delays and noise disturbance was analyzed by augmented state matrix method.Parametric expression of controller is given.The simulation analysis indicates that this system not only has the stability of loop-closed systems,but also decreases the information flow rate in network channels to fully use the network resources. |
