| 摘 要： | 研究了近地卫星基于严格回归参考轨道的轨道保持控制方法：将卫星编队理论引入单星绝对轨道保持控制，提出了"虚拟卫星编队"的概念，分析了卫星轨道相对于参考空间轨迹在轨道摄动情况下的偏离状态及变化趋势，然后根据卫星编队相对运动学，推导出了偏离状态与虚拟卫星编队构形参数之间的对应关系，并设计了以轨道参数超调、偏置及阈值触发为特征的管道保持控制策略。数值仿真结果表明，使用该控制策略能够将卫星轨道保持在以空间参考轨迹为中心的轨道管道内，并且有效减少了因周期性轨道摄动波动造成的管道保持控制量和控制频次。研究成果对于有空间轨迹回归要求的卫星轨道保持控制具有指导意义。

| Abstract: | The maintenance control method for strictly-regressive orbit of near earth satellites is investigated. Firstly, the satellites' formation flying theory is used in this control, and the concept of "virtual formation flying satellites" is proposed. Then, applying this concept, the satellite's tube radius error relative to the reference trajectory is simulated and analyzed. Based on the relative movement of formation flying satellites, the accumulated departure of the satellite is deduced using formation flying parameters and relative orbit elements. Furthermore, the tube maintenance strategy is designed, featuring the orbit elements overshooting, offsetting and threshold trigger. Finally, numerical simulation results show that the satellite's orbit could be controlled in the orbit tube with this strategy and the short-term periodic perturbation can be reduced effectively. The study can be used in the maintenance control of satellite's orbit with strictly-regressive orbit demands. |
