本文研究了导弹有制导盲区,目标做不变的加速运动及反导弹的机动运动两种情况下的最优制导律。对于前一种情况,以零控拦截曲面为目标集,以控制能量消耗最小为性能指标,应用最小值原理解之;对于后一种情况,以终端脱靶量及双方控制能量消耗之差为性能指标,以微分决策理论处理,得到了更为一般的最优制导规律。 In this paper, we study the optimal guidance law under both the missile guidance blind spot, the target invariant acceleration motion and the anti-missile maneuvering motion. For the former case, the zero-controlled interception surface is the target set, and the minimum energy consumption is controlled as the performance index, and the minimum principle solution is used. For the latter case, the difference between the terminal miss distance and the control energy consumption of both parties is the performance Indicators, differential decision theory to deal with, get a more general optimal guidance law.
