一种使用磁力矩器管理双自旋航天器角动量的方法
|
摘要
针对一种新型采用双自旋设计进行对地遥感任务的航天器,提出了一种使用磁力矩器对旋转载荷角动量进行管理的方法。使用旋转载荷固连正交安装的三只磁力矩器,在旋转过程中连续输出周期性变化的磁矩,使自转一周过程中产生的合角动量方向仅沿自转轴方向,避免在其他两轴方向产生角动量累积。该方法在工程上可行性好,仿真结果表明旋转载荷角动量持续保持在期望值附近,不随时间累加。
For a new kind of dual-spin spacecraft mission which is used for earth-observation, a method to manage the rotor's angular momentum with magnetic torquers is introduced in this paper. Three magnetic torquers fixed on the rotor part produce periodic magnetic momentum which contracts with Earth's magnetic field, balancing the angular momentum caused by friction of bearing while no angular momentum accumulation is caused to the other two axes. This method is applicable in engineering. Simulation shows that the total angular momentum of rotor converges to the desired value and does not accumulate over time.
