International audience. he problem of active Fault Tolerant Control (FTC) for a Polymer Electrolyte Membrane Fuel Cell (PEMFC) systems with time delays subject to an actuator fault, is investigated in this paper. This new approach consists on constructing an adaptive Unknown Input Observer (UIO) using linear parameter time varying model firstly and to design a control law secondly. Based on linear matrix inequality (LMI) techniques, the FTC linear parameter-varying (LPV) control scheme is developed for the LPV system. The stability of the proposed FTC via closed-loop system is verified by Lyapunov approach. Finally, the effectiveness of the proposed method is illustrated via simulation results.
