An extended FTC based on the MPD for the switched system

In the present work, we proposed a novel approach which allows the estimation of actuator fault and its compensation correctly for switched hybrid system. So, to thwart the impact of the fault we extended and developed a fault tolerant control (FTC) for switched system. The synthesis of it needs to follow three important steps. The first step, is based on the use of the Data-based Projection Method (MPD) to identify the fault perfectly. The second step, insures the estimation of the unavailable state utilizing the switched observer design. The third step is to calculate the nominal control, then combine it to an additive control already determined. This proposed method allows to the switched system to keep its performances in spite of occurrence of the actuator fault. An example is provided to confirm the significance of the proposed strategy.
