摘要: |
针对我国新一代全球导航星座长期构型维持控制问题,提出了MEO星座构型状态描述方法,分析了主要摄动力和轨道参数偏差作用下的星座构型演化规律,结合实测数据对稳定性规律进行了验证;研究了参数偏置摄动补偿控制原理,提出了一种改进的解耦控制方案,分析了星座部署时间对摄动补偿控制量的影响规律,得到了一些有益的关键性结论,为我国全球导航系统的星座构型设计和运控策略制定奠定了基础。 |

Abstract: |
Global navigation constellation maintenance is an important problem. Firstly, the model of MEO constellation formation was advanced. Then, with consideration of main perturbation forces and orbit ephemeris error, the constellation formation evolvement law was analyzed and asserted with some satellites orbital data. Also, anti-perturbation compensation strategy was put forward, an improved de coupling control method was proposed, and the effect of satellite launch time on anti-perturbation compensation strategy was discussed and analyzed. Finally, some key results were concluded as a summary, which will be helpful for the design of the global navigation constellation with inertial space and its maintenance and control strategies for its rotation around the earth. |
