Performance-based switching for fault tolerant control

Abstract This paper presents an approach to active fault-tolerant control (FTC) based on online closed-loop performance monitoring and experimental data without an explicit fault detection and isolation algorithm. The proposed approach sets forth the theory of unfalsified control to achieve a real-time control reconfiguration which is consistent with the performance objectives for a class of system faults. The obtained FTC scheme is an alternative or might be a complement to FTC methods based on explicit fault detectors and provides a precise and direct characterization of suitable real-time controllers for reconfiguration.
