摘要
高超音速导弹弹道优化的目的是针对其弹道数学模型,设计方案弹道,寻求一个最优攻角规律使得弹道性能指标最优.为此将弹道问题转化成最优控制问题,通过最小值原理,得到滑翔飞行距离最大的最优弹道的一阶必要条件,采用遗传算法求解了此两点边值约束问题.数值仿真算例表明,在满足状态方程约束条件下,通过最优控制解法和遗传算法求取最优弹道方法可行.
The goal of trajectory optimization attack angle so as to make trajectory scheme model, the fit trajectory law was considered mum principle was used to obtain first-order rithms, a two-point-boundary-value problem for a hypersonic missile is to find an optimal law of designed optimal. According to the trajectory math as an optimal control problem. Pontryaghin maxinecessary condition. By means of the genetic algowas resolved. Numerical simulation example shows that, under satisfying constraint conditions of equation of state, it is feasible to obtain the optimal trajectory by optimal control and genetic algorithm.
