Aiming at the problems of nonlinearity, coupling, multiple uncertainties and atmospheric disturbances in the longitudinal model of hypersonic vehicle, a robust control method based on signal compensation theory in this paper is proposed:the real model is divided into nominal model and equivalent disturbances,a state feedback controller is designed to achieve the desired tracking performance and a robust compensator is designed to restrain the influence of the equivalent disturbances. The results of numerical simulation show that compared with the state feedback control method, the robust control method proposed in this paper has better tracking effect and the control accuracy meets the requirements.
