In this paper, a nonsingular terminal sliding mode surface is proposed to investigate the stabilization problem of reusable launch vehicle(RLV) combined with finite time theory under lumped perturbation, which contains system uncertainty and external disturbance. Besides, adaptive law is utilized to estimate the unknown lumped perturbation. Theoretical analysis and rigorous proof indicate the global finite time stability of the closed-loop system, the settling time is given further. Finally, simulation results are provided to demonstrate the effectiveness of the proposed control law.
