摘要
导弹的主动段弹道设计及优化是提高导弹弹道射程的主要因素。以二级弹道导弹为例,建立导弹主动段的弹道射程优化模型,根据参数优化理论,提出一种基于单纯形-遗传算法的复合算法,该复合算法不仅具有较好的全局收敛性,而且具有精度高、收敛速度快的优点, 实现了主动段弹道的优化仿真,并与初始弹道进行比较验证。仿真结果表明,主动段终点的速度有效增大,射程提高32%,证明所提方法在弹道优化应用中是可行有效的。
Abstract
The design and optimization of active phase of the missile are very important for improving the missile's firing range. Taking the two-stage missile as an example, the trajectory optimization model of missile active phase is established. Then, a hybrid algorithm based on simplex method and Genetic Algorithm (GA) is proposed according to parameter optimization theory. The algorithm not only has fine global convergence performance, but also has fast convergence speed and high precision. Finally, the effectiveness of the proposed method is demonstrated by experiments. Compared with the initial trajectory, the velocity at the end point of the active phase is increased effectively, and the range is increased by 32%. Hence it is proved that the proposed method is feasible and effective for missile trajectory optimization.
