Résumé:
This paper presents an actuator fault compensation approach for a class of Linear Parameter-Varying
(LPV) systems with noisy measurements. The proposed method is based on interval estimation assuming
that the fault vector and the external disturbances are unknown but bounded. The main idea consists
in designing a control law, based on a linear state feedback, to guarantee closed-loop stability. An
additive control, based on fault bounds, is used to compensate the impact of actuator faults on system
performances. The closed-loop stability of the robust fault compensation scheme is established in the
Lyapunov sense. Simulation results are presented to show the effectiveness of the proposed approach.
