摘要：
Data fitting method has served as an effective way on control oriented modeling of hypersonic vehicle. In this paper, fitting method which based on unconstrained optimization theory is studied on the perspective of function approximation. A fitting model of winged-cone hypersonic vehicle is obtained using Levenberg-Marquard Method. Statistic theory is applied to choose fitting function. Through the analysis between raw data and fitting result, the method proposed in this paper has been proved its efficiency on approaching the aerodynamic model. A polynomial fitting model which supports the controller design of hypersonic vehicle has been provided.
