In order to satisfy the requirements of reentry vehicle attitude control under the uncertain fault and improve the robustness and adaptability of reentry control, a fault detection strategy and a attitude control method with actuator fault are introduced.For the dynamic model of reentry vehicle in fault case, a fault detection scheme is proposed by designing a nonlinear fault detection observer.An active tolerant tracking strategy is presented by making use of both adaptive control and sliding mode control techniques.Finally, simulation results are given to demonstrate the effectives of the developed fault tolerant control scheme.
