摘　　要：针对炸弹的弹体特性和"惯性/卫星"制导的特点,提出了中制导与最优末制导相结合的串联复合制导律。中制导通过程序实时解算最优攻角使炸弹升阻比最大以增加炸弹射程,末制导利用最优控制理论以最小的控制能量来保证足够大的弹着角,从而使得制导炸弹射程和杀伤威力都取得满意效果。并以某型"惯性/卫星"制导炸弹为例进行了仿真计算,仿真结果表明该方法有效可行,为"惯性/卫星"制导炸弹制导和控制系统设计提供了参考。Based on the analysis of the characteristics of the bomb and working mechanism of INS/SPS,a compound guidance law is proposed,consisting of midcourse guidance and optimal terminal guidance.In the midcourse guidance phase,best attack angle is obtained at real time,to get maximum value of lift-drag ratio.In terminal guidance phase,a big-enough trajectory angle of impact point is gained with least energy,according to optimal control theory.Larger range and better killing power of GB is correspondingly realized.And simulation is carried out for a certain type of GB,and simulation results confirm the efficiency of the compound guidance law,which in turn provide valuable basis for the design of GB control and guidance system.
