Abstract

This paper deals with the design and analysis of a switching stable control reconfiguration mechanism for compensating the effects of the abnormal functioning of sensors on the closed-loop system operation. Robust positive invariance based approach is followed aiming at detecting and isolating faults in the sensors. The main objective of the paper is to guarantee the fault detection, and isolation of the faulty sensors, which are switched off from the feedback control scheme in order to use only the healthy sensors. A parametrized controller is used to ensure the stability of the closed-loop system during switching satisfying a desired performance. Simulation results are used to illustrate the efficiency of the proposed active fault tolerant control scheme in preserving switching stability.
