摘　　要：针对被控对象为多输入多输出的网络控制系统,设传感器与控制器均为时间驱动,未能成功传输数据的传感器节点视为暂时失效,将网络控制系统建模为一类具有时变传感器"故障"的系统。此类系统相当于一个有限子系统的切换系统,借助容错控制和切换系统的理论,基于共同的Lyapunov方法,给出了闭环系统渐近稳定的充分条件以及控制器和观测器的协同设计方法。最后的仿真验证了方法的有效性。Considering a networked control system with an MIMO plant, the sensors and controllers are time-driven, the sensors failing to transmit data are treated to be invalidated temporarily, the networked control system is modeled as a system with time-varying sensors' fault. Such a system is a switched system with finite subsystems. With the theory of the fault-tolerant control and switched systems, the sufficient condition for the asymptotic stability of the closed-loop system is derived based on the common Lyapunov function, and the cooperative design approach of the controller and observer is given. Finally, the simulation validates the method.
