摘　　要：为了提高低轨遥感平台卫星用太阳帆板驱动机构(SADM,solar array drive mechanism)的速率稳定度,降低太阳帆板转动对星体姿态稳定度的影响,在对SADM驱动原理分析和驱动性能测试的基础上,明确了步进电机定位力矩对速率稳定度的影响,并提出了定位力矩补偿方法.在SADM转速和转矩测量平台上,对定位力矩补偿的驱动控制效果进行了测试和对比分析,测试结果表明,采用定位力矩补偿控制方法可以将SADM的速率稳定度提高约一倍.In order to improve the speed stability of solar array drive mechanism （SADM） used in a LEO remote sensing satellite and to reduce the effect of the motion of solar array on the satellite attitude stability, a compensation method for detent torque is proposed based on the detent torque analysis and testing results of direct drive SADM. A speed and torque testing equipment of SADM is used to test the driving performance with or without the detent torque compensation.The experimental results show that the speed stability of SADM is greatly improved.
