This paper presents an active fault tolerant control (AFTC) strategy for the more-electric aircraft suffering from total hydraulic loss. Based on linear quadratic regulator (LQR) and model reference control (MRC) method, the fault tolerant control law is reconfigured. A new model is adopted by regarding the control surfaces as independent ones. Without hydraulic power, the dissimilar redundant actuation system (DRAS) switches hydraulic actuators (HA) into electro-hydraulic actuator (EHA) to drive the control surfaces. Furthermore, by comparing different response performance of HA and EHA, the performance degradation is represented through the damaged aircraft model. Numerical simulation results validate the effectiveness of proposed AFTC strategy towards total hydraulic loss finally.
