针对一类具有传输时延的网络控制系统，提出了一种基于切换器的容错控制方法。马尔可夫链被用来描述传输延迟。然后，这类网络控制系统建模为马尔可夫跳变系统。提出了一种利用时滞状态信息和故障估计值的基于模糊控制器的故障控制方案，以保证故障系统的稳定性。一个倒立摆的例子说明了该方法的有效性。
In this paper, an observer-based fault-tolerant control (FTC) method is proposed for a class of networked control systems (NCSs) with transfer delays. Markov chain is employed to characterize the transfer delays. Then, such kind of networked control systems are modelled as Markovian jump systems. An observer-based FTC scheme using the delayed state information and the estimated fault value is presented to guarantee the stability of the faulty systems. An inverted pendulum example is used to illustrate the efficiency of the proposed method.
