Abstract: A robust backstepping control method based on auxiliary error compensation is proposed to solve the problem of amplitude and rate limitation of the actuator of the flexible Air-breathing Hypersonic Vehicle (AHV) model with parameter perturbation. The improved auxiliary system is used to ensure the stability of the closed-loop system and the boundedness of the tracking error when the amplitude and rate are constrained at the same time. The Finite-time-convergent Differentiator (FD) is used to realize effective estimation of the virtual instruction and its first derivative, and then a Nonlinear Disturbance Observer(NDO) is designed. The uncertainties of the model are estimated smoothly to further improve the control precision. The effectiveness of the proposed control method is verified by simulation.
