Interaction between fault diagnosis and controller reconfiguration in fault tolerant control


Abstract : Fault tolerant control (FTC) aims at ensuring that a technical process keeps fulfilling its main mission despite the presence of a malfunction. Examples of FTC include substituting a software sensor for a hardware sensor in case of significant performance degradation of the hardware sensor, or redistributing the control effort upon occurrence of an actuator fault. A fault tolerant control scheme typically consists of two parts, a fault diagnosis system aiming at detecting and locating possible malfunctions, and a reconfiguration mechanism that performs the required remedial actions. Up to now, most of the research works in this area deal with the design and the analysis of one of these parts, but the interaction between both parts is still not well mastered. The objective of the PhD project is to study this issue, which should help developing a systematic methodology for the design of fault tolerant controllers.
