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.

Key words： hypersonic vehicle; robust backstepping control; auxiliary error compensation; finite-time-convergent differentiator; nonlinear disturbance observer
