The invention relates to a high-orbit task replanning method for redesigning a parking orbit under a power fault, which comprises the following steps of: evaluating residual capability of entering the parking orbit when the power fault occurs, judging whether a vehicle can enter the original parking orbit, and if the vehicle can enter the original parking orbit, evaluating the residual capability of entering a target GTO orbit of the vehicle; if the target GTO track can be entered, the original target parking track and the target track do not change, and if the target GTO track cannot be entered, the parking track does not change, and the track closest to the original target track in shape serves as the target track; if the track cannot enter the original parking track, the parking track is not arranged any more, and the track with the maximum energy in the current track plane serves as a target track; according to the method, automatic and efficient matching of different thrust drop conditions and the predetermined transportation task completion degree is realized, the residual capacity evaluation precision is essentially improved, the design conservative property is reduced, the nonlinearity and variable coupling property of a standard planning problem is remarkably reduced, and the solvability of an optimization problem is improved.
本发明涉及一种停泊轨道再设计的动力故障下高轨任务重规划方法,包括:在发生动力故障时进行进入停泊轨道剩余能力评估,判断运载器能否进入原停泊轨道,若能进入原停泊轨道,则进行运载器进入目标GTO轨道的剩余能力评估,若能进入目标GTO轨道,则原目标停泊轨道与目标轨道不做变化,若不能进入目标GTO轨道,则停泊轨道不做变化,将最接近原目标轨道形状的轨道作为目标轨道;若不能进入原停泊轨道,则不再设置停泊轨道,将当前轨道面内能量最大的轨道作为目标轨道;本发明实现不同推力下降条件与预定运输任务完成度的自动高效匹配,从本质上提升剩余能力评估精度,降低设计保守性,显著降低标准规划问题的非线性与变量耦合性,提升优化问题可解性。
