摘要:

防空导弹的制导系统包含众多指标要素,目前对制导系统的优化往往只针对某个特定指标,但单个指标的最优并不代表综合性能最优,甚至可能出现单个指标更优但系统综合性能下降的情况。因此需要建立综合性能与各指标之间的数学关系,并寻找一种优化算法以同时满足综合性能优化和指标要素相关约束的需求。以“爱国者”-3防空导弹为研究目标,建立了制导系统性能评估体系,针对过程约束及目标函数,使用一种单纯形与增广拉格朗日相结合的方法对制导系统进行优化。仿真结果表明,该方法可有效提高制导系统的综合性能。

Abstract:

The guidance system of air defense missile contains many index elements. The current optimization of the guidance system is often only for a specific index, but the optimization of a single index does not mean the optimal comprehensive performance, or even the situation that a single index is better but the comprehensive performance of the system decreases. Therefore, it is necessary to establish the mathematical relationship between comprehensive performance and each index, and find an optimization algorithm to meet the needs of comprehensive performance optimization and relevant constraints of index elements at the same time. Taking Patriot-3 air defense missile as the research goal, the performance evaluation system of guidance system is established. A combined simplex and augmented Lagrangian method is used to optimize the guidance system with respect to the process constraints and objective functions. The simulation results show that this method can effectively improve the comprehensive performance of the guidance system.

Key words: air defense missile, guidance system, system optimization, simplex method, augmented Lagrange
