Résumé:
This paper addresses the problem of passive Fault Tolerant Control (FTC) for Linear Parameter-Varying (LPV) systems subject to actuator faults. The FTC, based on a linear state feedback, is designed to
compensate the impact of actuator faults on system performance by stabilizing the closed-loop system
using interval observers. The design of interval observers is based on the discrete-time Luenberger observer
structure, where uncertainties and faults with known bound s are considered. Sufficient conditions for the
existence of the proposed observer are explicitly provided. Simulation results are presented to show the
effectiveness of the proposed approach.
