N2 - This paper investigates the attitude control problem for flexible hypersonic vehicle based on back-stepping method with a non-linear disturbance observer, especially when the lower frequency of elastic vibration is closed to the system bandwidth. First, the flexible dynamic model of the pitch channel concerning Aeroservoelastic is derived, where the elastic vibration is taken into consideration. Then treated as external disturbance to attitude sensors, a nonlinear disturbance observer is designed to estimate the elastic vibration so as to be compensated. Afterward, a back-stepping attitude controller is designed with the compensation to the attitude sensor measurement, and the rigorous stability analysis for the closed-loop system is presented. Finally, the effectiveness of the proposed control scheme is validated by numerical results.
