摘　　要：针对短时延情况，本文利用容错的思想建立了SISO（Single-Input Single-Output）网络控制系统发生传感器故障时的模型。在此基础上，借助切换系统理论分析了闭环网络控制系统的稳定性。用LMI形式给出了系统渐近稳定的充分条件和控制器的设计形式，最后给出了仿真证明。For Single-Input Single-Output （SISO） NCSs with short delay, the model of NCSs with sensor failure is established in this paper. Furthermore, on the basis of the aforementioned model, the stability of close-loop NCSs is analyzed by means of switched systems. A design method of controller possessing integrity to sensor failure is presented by solving a set of LMIs. Lastly, some illustrative examples and simulation results are provided to demonstrate the effectiveness of the proposed design method in this paper.
