The problem of robust fault tolerant control for continuous-time fractional-order (FO) systems with interval parameters and sensor faults of 0<α<2 has been investigated. By establishing sensor fault model and state observer, an observer-based FO output feedback controller is developed such that the closed-loop FO system is asymptotically stable, not only when all sensor components are working well, but also in the presence of sensor components failures. Finally, numerical simulation examples are given to illustrate the application of the proposed design method
