采用 DGCMG 的空间站扰动辨识动量管理

研究长期在轨空间站的动量管理问题。针对动量管理过程中力矩平衡姿态的求解与稳定性进行分析，应用李亚普诺夫方法，给出一种考虑常值姿态干扰的动量管理控制方法，使用双框架控制力矩陀螺作为姿态控制执行机构，进行动量管理控制仿真。仿真结果表明该方法控制准确、收敛快速，可以作为空间站姿态控制的工程参考。

Momentum Management and Disturbance Identification of Space Station Using DGCMG

This investigation focuses on the momentum management of a long-term orbiting space station.Firstly, the solution and its stability of Torque Equilibrium Attitude during momentum man-agement were analyzed .Then a momentum management controller considering a constant attitude disturbance was given using Lyapunov theory .Finally the momentum management control simulation was carried out to illuminate it with the steering law of parallel mounted DGCMG .It is proved that the control result is correct and convergent .The momentum management controller can be applied to the attitude control of space station .
