标题： Fast Optimization of Impulsive Perturbed Orbit Rendezvous with Finite Iterations

摘要： 提出了一种新的长时间摄动轨道交会多脉冲快速优化方法。 首先，基于解析估计的脉冲，利用精确的动力学模型可以预测终端交会偏差。 然后，根据圆轨道解析J2摄动动力学方程，可以基于轨道元素的偏差计算出脉冲的解析修正。 随后设计了重复预测和校正的迭代过程，以快速获得精确的解和轨迹。 仿真结果证明，该迭代方法很好地适应了解析动力学和高精度动力学。 偏差总能在五次迭代内收敛。 显示英文摘要

摘要： A novel fast multi-impulse optimization method for long-duration perturbed orbit rendezvous is proposed. First, based on the analytically estimated impulses, the terminal rendezvous deviation with precise dynamics model can be predicted. Then, an analytical correction to the impulses using the deviations of orbit elements can be calculated based on the analytical J2 perturbed dynamics equation of a circular orbit. The iteration process repeating prediction and correction is then designed to quickly obtain a precise solution and trajectory. The simulation results proved that the iteration method adapts well to the analytical dynamics and high-precision dynamics. The deviation could always converge within five iterations.
