摘　　要：针对实际应用中传感器失效率时变的特点,运用Markov状态转移的方法,构建网络控制系统可靠性的模型,并推导出其可靠性的大小。最后分别选取传感器失效率对正弦变化和指数变化的网络控制系统进行仿真,仿真的结果证明了所提出的方法是正确的。Concerning the characteristics of the time-varying failure rate of sensors in practical application, the method of Markov state-shifting was used, a reliability model of Networked Control System （NCS） was designed and its reliability was deduced. Finally, simulations have been done with sensors of sine-varying and exponential-varying failure rate, and the results show that the proposed method is correct.
