Consistency-based failure detection and reconfigurable control

容错控制是基于检测和识别故障并使控制回路适应故障对象的技术。这一领域的研究通常要么涉及故障诊断步骤，要么涉及控制器对给定故障情况的调整，而将这两个步骤结合起来形成完整的容错控制方法的方法很少。该项目旨在将传感器或执行器故障检测方法与重新配置方法相结合，该方法通过用替代部件更换故障传感器或执行器来使控制回路恢复运行。这个想法是使用工厂的结构表示来找到有故障的部件，并用替代部件替换这些部件。基于一致性的故障检测方法和前期工作中阐述的重新配置方法的扩展版本应整合并应用于试点工厂。该项目是与捷克布拉格理工大学控制工程系合作项目的一部分。该项目的另一部分已提交给捷克共和国赠款机构(GA CR)。

Fault-tolerant control is based on techniques for detecting and identifying faults and foradapting the control loops to the faulty plant. Research in this field typically deals either with thefault diagnostic step or with the controller adjustment to a given fault situation and only a few approaches have been proposed for combining both steps to a complete fault-tolerant control method. This project aims at combining methods for sensor or actuator failure detection with a reconfiguration method that brings the control loop back into operation by exchanging the faulty sensor or actuator by alternative components. The idea is to use a structural representation of the plant to find the faultycomponents and to replace these components by alternative ones. A consistency-based failure detection method and an extended version of the reconfiguration method elaborated in preliminary work should be integrated and applied to a pilot plant.The project is part of a cooperative project with the Department of Control Engineering of the Czech Technical University Prague. The other part of the project has been submitted to the Grant Agency of the Czech Republic (GA CR).
