中文摘要：
研究了具有不确定时延的动态输出反馈网络控制系统鲁棒控制器设计问题．考虑小于等于一个采样周期的不确定时延，将动态输出反馈网络控制系统建模为含有不确定性的离散时变系统．利用Lyapunov理论和矩阵不等式方法，推导出系统鲁棒控制律存在的条件，并转化为矩阵不等式表示的可行性问题，从而可利用MatlabLMI工具箱来求解，以便构造鲁棒控制律．Matlab仿真算例说明分析方法和结果是有效可行的．
英文摘要：
The problem of robust controller design for dynamic output feedback networked control systems with tmcertain time-delay is studied. Considering time-delay less than and equal to one sampling period, the system is modeled as a discrete time-variant system with tmcertainty. By using the Lyaptmov theory and linear matrix inequality method, the condition of existence of robust control law for the dynamic output feedback system is derived and transformed as the feasibility problem described by linear matrix inequality, which can be solved by Maflab LMI toolbox to obtain the robust control law for a class of system. A Matlab simulation example is given to illustrate that the analysis method and the result are valid and feasible.
