In this paper, a Fault Tolerant Control (FTC) scheme using virtual actuators for discrete-time polytopic Linear Parameter Varying (LPV) systems subject to actuator saturations is proposed. The plant with the faulty actuator is augmented to take into account the saturations and modified adding the virtual actuator block that masks the fault. The elements of the FTC control loop are designed using Linear Matrix Inequalities (LMIs) in order to achieve the Pole Placement and the H2 norm specifications. To assess the performance of the proposed approach an aeronautical application is used.
