卫星相位保持的多冲量次优控制

Satellite Phase Keeping for Multi - Impulse Hypo - Optimal Control

在推导了多冲量最优解的必要条件的基础上，给出了一种卫星相位保持的多冲量次优控制方法。由于摄动和截断误差等对控制的影响，在多次冲量的求解时应该使用中间修正。计算表明，加中间修正的多冲量次化控制方法具有很好的鲁棒性。

Based on derived essential condition of multi - impulse hypo - optimal solving,a multi - impulse hypo- optimal control method for satellite phae keeping is presented. Be-cause of the effect of perturbation and truncation error and so on, we need to use intermediate correction for multi- impulse solving. The computation results indicate that adding interme-diate correction for multi- impulse hypo- optimal control method hare good robustness.
