In this paper, active disturbance rejection control technique is presented for the rigid-aeroservoelasticity(ASE)-sloshing hypersonic vehicle model subject to uncertainties and external disturbance. The statically unstable hypersonic vehicle model outlined here takes into accounts the interactions between liquid sloshing and flexible structure of aircraft. In order to overcome the high nonlinearity, strong coupling and uncertain factors, cascade linear active disturbance rejection controller(LADRC) is utilized to estimate and eliminate internal uncertainness and exogenous disturbances. Finally, simulation results show that the effectiveness of the proposed controller which is validated by the nonlinear model and the proposed method exhibits promising robustness to mismatched uncertainties.
