The invention discloses a midway correction method for an earth-moon L2 point transfer track, and the method comprises the steps: determining a speed increment needed by midway correction according tothe track state of the transfer track at a certain moment and a terminal target requirement, and enabling a detector to meet the terminal state requirement of entering the earth-moon L2 point track under the condition that there is an error in the transfer track. According to the method, the dynamic characteristics of the earth-moon L2 point orbit are ingeniously utilized, the speed component passing through the XOZ plane of the earth-moon convergence coordinate system is selected as a control target, the stable terminal requirement of the earth-moon L2 point orbit is met, and the engineeringoperability is guaranteed; and meanwhile, the successive iteration of the hierarchical targets is adopted, so that the convergence of the algorithm is ensured.

    本发明公开了一种地月L2点转移轨道中途修正方法,根据转移轨道某时刻的轨道状态和终端目标要求,确定中途修正所需的速度增量,使探测器在转移轨道存在误差的情况下,满足进入地月L2点轨道的终端状态要求。本发明巧妙地利用地月L2点轨道的动力学特性,选取了经过地月会合坐标系XOZ面处的速度分量作为控制目标,满足了地月L2点轨道稳定的终端要求,保证了工程的可操作性;同时采用了分级目标的逐次迭代,保证了算法的收敛性。
