时变延时现象的存在是网络控制系统容错控制的一个巨大难题,该文对具有时变延时网络控制系统容错控制的研究进行了总结,在前人研究成果的基础上,提出了一种时变延时网络容错控制算法.首先提出了一个带有不同时间延迟和传感器或执行器故障的网络控制模型,通过改变采样周期,将数据传输引起的时间延迟限制在一个采样周期内,然后用稳定性理论设计容错控制算法.仿真实验结果证明,将该算法应用于时变延时网络控制系统是可行的、有效的.

Time-varying delay phenomenon of network control system is a huge problem of fault-tolerant control,through the network control system with time-varying delay fault tolerant control research are summarized,and on the basis of predecessors’research results,this paper has proposed a time-varying de-lay network fault tolerant control algorithm.First,a with different time delays and network control model of sensor or actuator failure has been put forward by changing the sampling period,and it will cause the time delay of data transmission limit within one sampling period by means of stability theory to design fault tolerant control algorithm.The simulation experimental results show that the algorithm is applied to time-varying time delay network control system is feasible and effective.
