摘　　要：直接多重打靶算法是求解最优控制问题很有效的方法之一。通过仅假设出节点处的控制变量值,使该算法在求解最优控制问题时更方便,收敛更快。利用改进算法成功地求解了多个飞行力学问题,探讨了敏捷性管理系统的优化设计。通过优化设计,使敏捷性管理系统在确保满足各种约束条件的前提下,飞机的转弯时间缩短了近20%。The direct multiple shooting algorithm is one of the very effective methods of solving optimal control problem. Some of the optimal control problems can be solved more quickly and efficiently with the algorithm if only the control variable's values at the knots are given. Some flight dynamics optimal control problems were solved successfully with the improved algorithm. The algorithm is applied to solving the problem in optimal design of combat agility management system (CAMS) in this paper. The study results show that by adopting CAMS designed with the optimal control theory , an aircraft's turning time can be shortened by about 20%.
