Aiming at the parameter uncertainties and severe Aeroservo elasticity of hypersonic vehicle under high dynamic pressure, an adaptive sliding mode control method based on elastic backstepping is proposed.Based on the longitudinal dynamics model of the elastic hypersonic vehicle, the backstepping design method is used to ensure the stability of the system state, in order to eliminate the influence of uncertainties, an adaptive sliding mode controller for elastic hypersonic vehicle is designed.The simulation results show that the method can effectively suppress the effects of uncertainties and Aeroservo elasticity.
