Fault-tolerant control aims at modifying a given controller in case of a fault such that the controlled faulty plant again fulfills its task. For this, the steps of fault diagnosis and reconfiguration of the controller are essential, which mainly have been treated independently from one another in literature. The aim of this project is to develop a method for fault-tolerant control of discrete-event systems which combines methods for the active fault diagnosis with a reconfiguration approach exploiting available redundancies. The main idea is to unambiguously determine the state and the behavior of the plant after the occurrence of the fault in order to modify the plant's desired trajectory appropriately. A consistency-based diagnostic method based on the theory of testing of automata is to be combined with a reconfiguration method employing a local search, where both methods have been developed in preliminary work in the group of the applicant. The applicability of the new integrated method shall be demonstrated by applying it to a pilot plant.

容错控制的目的是在发生故障时修改给定的控制器，使被控制的故障设备再次完成其任务。为此，控制器的故障诊断和重构是必不可少的步骤，在文献中这两个步骤主要是相互独立处理的。本项目的目的是开发一种离散事件系统的容错控制方法，该方法将主动故障诊断方法与利用可用冗余的重构方法相结合。其主要思想是在故障发生后明确地确定装置的状态和行为，以便适当地修改装置的期望轨迹。基于自动机测试理论的基于一致性的诊断方法将与采用局部搜索的重新配置方法相结合，其中两种方法都是在申请人小组的初步工作中开发的。新的综合方法的适用性应通过将其应用于试验工厂来证明。
