基于MOEA/D算法的多脉冲末修子弹多目标优化设计研究

针对多脉冲末修子弹设计中脱靶量、落地时间、弹着角等优化目标间的强烈冲突性问题,以其修正段为研究对象,建立了以初始高度、初始落速、单个脉冲发动机冲量为决策变量,以打靶误差、落地时间、弹着角、脉冲发动机耗能为目标函数的三种多目标优化模型,并采用MOEA/D算法进行仿真计算.结果表明:所求Pareto最优解较符合工程实际问题,有助于设计人员选择合理参数优化弹道,对多脉冲修正子弹的总体设计有着重要的参考意义.

The Research on Multiple-impulse Correction Submunition Multi-objective Optimization Based on MOEA/D

In the design of multiple-impulse terminal correction submunition,in view of the intensively conflictive problem among the optimization objectives,three multi-objective optimization models based on the decision variants "initial height,initial velocity and the impulse of the single thruster controller" and the objective functions "the miss distance,the drop time,the angle of the projectile falling on the ground and the total consumed energy" were established,here terminal correction trajectory was taken as the object of research.The algorithm of MOEA/D was adopted in the simulation.The simulation results indicate that the Pareto frontier we get is suitable for real and engineering problems,which is helpful for designer to choose appropriate parameters to optimize trajectory and provides designers with great consultative value.
