An inertia-free fault-tolerant attitude tracking law is proposed for a lifting reentry vehicle with the actuator faults. The proposed control law is based on the backstepping control. The effect on attitude control performance by the external disturbance is also suppressed by the proposed control law. The stability of the control law is ensured. Furthermore, the relationship between the upper bound of the tracking error and the design parameter is also given in this paper. To demonstrate the efficiency of the method, the simulation of X-33 vehicle in reentry mode is carried out.

Key words: Reentry vehicle, Attitude tracking, Fault tolerant control, Backstepping control
