In this paper, an integrated fault-tolerant guidance and control scheme is proposed for reentry hypersonic vehicles. Firstly, a predictor-corrector reentry guidance controller in guidance loop is designed for guidance commands to generate the desired angle of attach and bank angle commands that satisfy the reentry constraints. Then, a backstepping control algorithm is designed for attitude loop to track the desired guidance commands. Through a control allocation approach, the required control surface deflections are calculated. The control surface faults are considered and the remaining healthy control surfaces are distributed in an optimal way to compensate the influence of the failed surface. Simulation results under different scenarios, including both normal and fault situations, are presented to show the performance of the proposed integrated guidance and control scheme.
