摘　　要：针对具有时延和参数不确定性的网络控制系统的研究。考虑系统的时延小于一个采样周期,传感器是时钟驱动,控制器和执行器是事件驱动。当执行器发生故障时,研究网络控制系统的H∞容错保成本控制。依据所描述情况建立系统模型,基于Lyapunov稳定性理论、容错控制理论和线性矩阵不等式(LMIs)处理方法,推导出网络控制系统是渐近稳定的,并且得出系统的H∞容错保成本控制的充分条件和系统的保成本上界。实例仿真证明结论的有效性。This paper studies the network control system with time delay and the uncertainty parameters. In view of the system of the time delay less than one sampling period, sensor is the clock driver, controller and actuator is event driven. Considering actuator fault, the network control system is Hinfinity fault tolerant guaranteed cost control. According to the description, this paper establishes a system model. Based on the Lyapunov stability theory, faulttolerant control theory and linear matrix inequality processing methods, network control system introduced is asymptotically stable. And sufficient condition of Hinfinity faulttolerant guaranteed cost control and upper bound of the guaranteed cost system are given. An application simulation results prove the effectiveness of the conclusion.
