Consistency-based failure detection and reconfigurable control

点击翻译按钮获取中文摘要

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).
