摘要：
In virtue of the precise linearization function of nonlinear dynamic inversion, a drag acceleration-energy trajectory tracking law is proposed combined with H∞ control method. By dynamic inversion, the nonlinear hypersonic vehicle system is equivalent to a linear object. Considering both unstructured uncertainties and parametric uncertainties, the H∞ control method is employed to design a robust controller so as to achieve good tracking performance. Robust stability of the closed-loop system under this tracking law is proved. Simulation results show the effectiveness of the proposed method.
