In this paper, a backstepping fault-tolerant control scheme is proposed, enabling hypersonic reentry vehicles which are only controlled by reaction control system with unknown actuator faults and external disturbances to accurately track the attitude commands. Firstly, a control-oriented hypersonic reentry vehicle model which regards two factors mentioned above as lumped disturbance are stated. Then, a high-order sliding mode observer is used to estimate and compensate the lumped disturbance and achieve the purpose of anti-disturbance. Based on the disturbance observer and back-stepping control method, the proposed fault-tolerant control scheme is designed. Meanwhile, considering the characteristic of reaction control system, specific control allocation and PWPF modem are adopted in the control scheme. Finally, the stability and effectiveness of the proposed controller are verified from theoretical analysis and numerical simulations respectively.
