摘要：

Since hypersonic vehicle involves characteristic of nonlinearity, strong coupling, uncertainty and so on, the method of integrated design on the modeling and control for hypersonic vehicle is proposed. This method first regards geometrical shape with typical structure of hypersonic vehicle as research object, and establishes vehicle's nonlinear longitudinal model equations combining with the theories of hypersonic aerodynamics; Then gets several trim points at various flight conditions, and analyzes flight aerodynamic characteristics, further designs the controller with nonlinear decoupling control ability in each trim point, and integrates controls parameters obtained of several trim points, thereby realizes non-stop flight in several trim points by interpolation calculation; Finally, the simulation results show that the method introduced in this paper is feasible.
