| 摘 要： | 根据磁力矩在地磁场中的定向阻尼特性，提出了磁控重力梯度和有阻尼器的非重力梯度卫星姿态控制律。给出了卫星姿态运动方程，并证明采用两种方法控制卫星姿态的稳定性。根据地磁场强度变化规律选择控制系数。理论分析和仿真结果表明，基于磁力矩定向阻尼特性的卫星姿态磁控制方法简单、精度较高。

| Abstract: | According to the direction and damping characteristic of the torque produced by the magnetic torques, the three-axis attitude control schemes of gravity gradient satellite and other satellite with damper were put forward in this paper. The attitude motion equation of satellite was given, and the attitude of magnetic control for gravity gradient satellite would go to stable. The attitude control precision was improved through control coefficients, which were determined by the dynamic characteristics of geomagnetic interisity. The theory analysis and simulation results showed that the control law was simple and the attitude precision was high. |
