In this paper, an active Fault Tolerant Control (FTC) strategy is developed for Switched Hybrid Systems. The main contribution concerns the design of a linear Output Feedback dedicated to Switched Hybrid System. Based on an available Fault Detection, Isolation (FDI) scheme, the controllers redesign is performed on-line trough LMI both in fault-free and faulty cases in order to preserve the system closed-loop stability despite of actuator failures. The effectiveness and performances of the proposed FTC method are illustrated in a simulation example.
