This paper presents a FTC scheme for a quad-plane using sliding mode control allocation. The scheme presented in this paper takes full advantage of the redundant vertical rotors to handle total actuator failures, especially during forward flight. The scheme utilises a combination of sliding modes and control allocation which requires only a single baseline control to be designed that operates in both fault free and fault/failure conditions. The scheme exploits the robustness of sliding modes to deal with actuator faults and control allocation to redistribute the control signals in the event of total actuator failures. Simulation results on a nonlinear model of a quadplane shows the efficacy of the scheme.
