摘要

针对制导滑翔炸弹的最远滑翔距离问题,提出一种基于动态规划的制导律设计方法.对制导炸弹受力和滑翔控制约束进行分析；按照最优化分析方法建立制导滑翔炸弹的数学模型；根据末端着地角约束的特点,设计了顺序搜索的动态规划算法.最后,根据制导炸弹实际飞行情况,确定了各项约束的参数,按照设计的算法进行了寻优计算.计算结果表明了该方法的有效性.%An guidance law design method based on the dynamic programming was proposed for the extreme gliding range problem of the guided glide bomb. The force and control constraints of the guided glide bomb were analyzed. Then, a mathematical model of guided glide bomb was established by using the optimization analysis method. The dynamic programming algorithm of sequential search was designed based on the characteristic of impact angle constraint in the end. Finally, all the constraint parameters were ascertained according to the actual guided glide bomb flight. Optimization calculation was implemented based on ihe designed optimization algorithm. The calculation result showed the effectiveness of the proposed method.
