研究了在真实空间环境中椭圆轨道上长期稳定伴飞的构型设计和构型保持控制方法。基于椭圆轨道航天器相对运动方程,推导出周期性相对运动条件,给出了两种稳定伴飞构型,用闭环控制和基于轨道要素的伴飞控制两种方法进行伴飞构型的长期稳定控制,并对结果进行比较,评估了两种控制方法的精度和工程适应性。仿真结果证明了两种方法的正确性和有效性。

The design and control methods for long-term stable companying flying on an elliptical orbit under real space environment were studied in this paper.The condition of periodic relative movement was deduced based on the spacecraft relative motion equation of elliptical orbit.Two stable companying flying configurations were given out.Two methods for long-term stable configuration control which one was closed-loop control and the other was based on orbital elements were applied to control.The results of two methods were compared and the precision and engineering applicability of control methods were evaluated.The simulation results proved the correctness and validity of the two methods proposed.
