考虑了圆形受限三体问题中沿振动点轨道飞行的站位保持和编队问题。为了处理相对于参考轨迹的相对运动，本文扩展了前人的研究，导出了基于输出调节理论的站位保持控制器。首先，假设参考轨道由截断的傅立叶级数给出，主卫星的参考轨道被表示为一个称为外系统的自治系统的输出。对于编队飞行，副卫星相对于主卫星的相对轨迹也用外系统的输出来表示。在此基础上，通过对两个系外系统的叠加得到编队飞行渐近跟踪的参考信号。将所提出的控制器应用于沿日地l2点周期轨道飞行的保持和编队，并进行了验证。
Station-keeping and formation flying along a libration point orbit in the circular restricted three-body problem are considered. In order to deal with the relative motion with respect to a reference trajectory, this paper extends our previous study which derives the station-keeping controller based on the output regulation theory. First the reference orbit of the chief satellite is represented as the output of an autonomous system called exosystem, assuming the reference orbit is given by a truncated Fourier series. For the formation flying, the relative trajectory of the deputy satellite with respect to the chief satellite is also represented by the output of an exosystem. Then the reference signal to be asymptotically tracked for the formation flying is obtained by the superposition of the two exosystems. The proposed controllers are applied and verified for the station-keeping and formation flying along a periodic orbit of the Sun-Earth L 2 point.
