提出了一种状态可测的确定性输入/输出（I/O）自动机建模的离散事件系统的容错控制方法。该方案包括一个诊断单元和一个重新配置单元，以检测和识别故障，并重新配置由轨迹规划单元和控制器自动机组成的控制器。在控制器的重新配置期间，到期望的最终状态的轨迹被重新规划，并且控制器自动机通过移除和添加某些转变而被修改。证明了在所提出的容错控制回路中，如果控制回路是可恢复的，则故障对象在没有任何外部干预的情况下达到期望的最终状态。
A method for the fault-tolerant control of discrete event systems modeled by deterministic input/output (I/O) automata with measurable state is proposed. The scheme consists of a diagnostic unit and a reconfiguration unit in order to detect and identify the fault and to reconfigure the controller consisting of a trajectory planning unit and a controller automaton. During the reconfiguration of the controller, the trajectory to the desired final state is re-planned and the controller automaton is modified by removing and adding certain transitions. It is proved that in the proposed fault-tolerant control loop the faulty plant reaches the desired final state without any external intervention, if the control loop is recoverable.
