摘　　要：考虑实际模型的不确定性,针对一类长时延网络控制系统,建立起一类不存在数据包丢失及数据时序错乱的长时延线性离散系统,并将无源控制引入网络控制系统,运用线性矩阵不等式(LMI)和Lya-punov理论,推导出闭环系统渐近稳定且满足鲁棒无源性的充分条件,并给出无源控制器的设计方法,通过Matlab数值仿真算例,证明分析方法和结论的有效性。This paper studies the robust passive control of a class of network control systems with long time delay. Suppose that the generalized plant is modeled as a linear discrete system without data packed dropout and time sequence in disorder, The passive control is introduced in NCS in this paper. Based on linear matrix inequality （LM1） and lyapunov function, a sufficient condition for NCS which is subject to the asymptotic stability and robust passive performance is derived, and the design approach of the controller was also given, A numerical simulation example with Matlab shows that the analysis method and results are valid and feasible.
