摘要
Abstract
A Characteristic Parameter Trajectory Optimization Method (CPTOM) for the ascent phase of the air-breathing vehicle was proposed and studied. The expression for aerodynamic force and thrust were specially studied, and the motion equations were founded. According to the characteristics of the ascent motion of air-breathing hypersonic flight vehicle (AHFV), the control variable models based on exponential and polynomial functions were established. The models were determined by several characteristic parameters to be optimized. So the optimal control problem was translated to a nonlinear programming problem which can be calculated by the Sequence Quadric Programming (SQP). Because of the sensitivity of the initial value for optimization, the Genetic Arithmetic (CA) and Manual Method (MM) were proposed for initial value guess.关键词
