Firstly, the conception of hypersonic flight and its flight characteristics are introduced in the article. Secondly, a control method based on the structured singular value theory is proposed, and the necessity of this method whether can be applied to design the hypersonic vehicle controller is discussed. And then taking a model for example, the robust controller of hypersonic vehicle is designed. At last, the control effect of this controller is proved better through the simulation result. It also turned out that the controller has excellent command track performance.
