摘　　要：针对卫星制导炸弹高度测量误差较大的缺点,利用最优控制理论设计了一种带落角约束的最优末制导律。为满足快速解算的需求,基于遗传算法优化得到次最优末制导律,使制导炸弹以陡峭的弹道攻击目标,消除高度误差对制导精度的影响。仿真结果表明:炸弹着地时弹道倾角接近-90°,法向需用过载远小于可用过载,具有良好的毁伤效果,末制导律制导精度高,鲁棒性强。According to the fault of the satellite guided bomb with larger height measurement error, an optimal terminal guidance law with the fall angle constraint is designed by using the optimal control theory. In order to meet the demand of fast calculation,a suboptimal terminal guidance law is optimized based on genetic algorithm,the target is attacked by the guided bomb with a steep trajectory,the effects of height error on guidance accuracy is eliminated. The simulation results show that when the bomb hit the ground,the trajectory angle closes to -90° ,the normal required overload is far less than the available o- verload,damage has good effect,the guidance law has high precision and strong robustness.
