一种新型闭路制导方法

为提高大干扰条件下传统摄动制导的精度,提出了一种不同于基于需要速度的新型弹道导弹闭路制导方法。利用最优控制,根据能量消耗最少准则建立一种迭代解法,控制导弹最终状态在零控曲面上某一点关机,之后以惯性飞行即能命中目标。给出了零控曲面的求解模型,以及最优控制迭代解法的步骤、导航计算和关机条件。

One New Close Loop Guidance

To improve the low precision of classic perturbation guidance under large disturbance,a new close loop guidance law for ballistic missile was put forward in this paper,which was different from the old one based on the requirement velocity.An iterative algorithm was established by optimal control according to minimization the energy in the control process,which would control the final state of the missile on the zero control curved surface to shut off the engine.Then the missile would fall on the target freely.The solution model for the zero control curved surface was given out,and so were uhe steps of iterative algorithm of optimal control,navigation calculation and the shut-off condition of the engine.
