摘要: 推导了椭圆轨道编队的一些典型构形模态,指出椭圆轨道卫星编队的模态不同于圆轨道的构形模态,是极为丰富的。基于T-H方程的解析解,推导了副星在沿航向常值推力作用下的椭圆轨道编队的构形变化控制方法。推导的构形变化控制方法,通过合理的选择控制量的作用时刻,可达到大量节约燃料的目的。最后,给出仿真算例。

Abstract: Some formation modes of spacecraft formation flying in eccentric orbits are derived.The formation modes in eccentric orbits are more than the formation modes in circular orbits.Based on the Tschauner-Hempel equation the formation control algorithm for spacecraft in eccentric orbits is put forward.The control acceleration is on the track of orbit and is fixed in this control(algorithm).The control schedule is optimized in order to economize fuel.Furthermore,numerical(examples) and simulation results are also given to verify the effectiveness of the algorithms proposed above.
