高超声速助推-滑翔导弹的弹道优化问题涉及攻角、法向过载、最大动压等多种约束条件，是一种复杂的最优控制问题。序列二次规划法（ SQP ）是解决该类问题行之有效的数值优化方法。首先给定了助推-滑翔导弹助推段的动力学方程并建立数学模型，之后利用SQP算法对助推-滑翔导弹助推段进行弹道优化仿真，获得满足各种约束条件的优化弹道。经分析可得SQP算法可以为导弹助推段寻找到一条最优弹道，从而为助推-滑翔导弹的整体结构设计提供了有益的参考。

The trajectory optimization of the hypersonic booster-gliding missile is a kind of complex optimal control problem. It involves a variety of constraint limits, such as attack angle, normal overload, the maximum dynamic pressure and so on. The Sequential quadratic programming method (SQP),which has the advantage of short optimization time and high calcula-tion precision, is an effective numerical optimization method to solve the problem. In this paper, the SQP is applied to opti-mize the booster trajectory of the booster-gliding missile, and then getting the optimal trajectory which satisfies a various of constraint conditions. providing the beneficial reference for the integral structure design of booster-gliding missile.
