摘　　要：目的将无源控制引入网络控制系统,研究一类长时延网络控制系统的无源控制问题.方法运用线性矩阵不等式(LMI)和Lyapunov理论,推导闭环系统渐近稳定且满足无源性的充分条件及无源控制器的设计方法.结果提出了一类长时延网络控制系统的模型,分析了闭环系统渐近稳定且满足无源性的充分条件,并给出无源控制器的设计方法.结论通过设计无源控制器,使长时延网络控制系统的性能有了很大改善,通过Matlab数值仿真算例,证明了分析方法和结论的有效性.This paper studies the passive control of a class of network control systems with long time - delay. Suppose that the sensor node is time driven, the controller and actuator of the networked control systems （NCS） are event driven, 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 （LMI） and lyapunov function, a sufficient condition for NCS which is subject to the asymptotic stability and passive performance is derived, and the design approach of the controller is also given. A numerical simulation example with Matlab shows that the analysis method and results are valid and feasible.
