ESO-based backstepping control for air-breathing hypersonic vehicle with acceleration feedback

Abstract

This paper studies the tracking control problem of airbreathing hypersonic vehicles subjected to complicated and uncertain property of the aerodynamic characteristics. An ESO-based backstepping control scheme with acceleration feedback is proposed. The control scheme includes inner and outer loops. The outer loop is designed by backstepping method, which is incorporated with acceleration feedback. And the extended state observer is involved to compensate the compound disturbance. The inner loop is designed by dynamic inversion method to track the virtual control signal of the outer loop. Lastly, numerical simulations are conducted to verify the performance and effectiveness of the control scheme.
