摘　　要：根据无刷直流电动机的工作原理,针对圆锥扫描式红外地平仪对电机转速稳定性的特殊要求,建立了电机转速的数学模型,对电机驱动系统各环节进行设计,通过研究、分析、仿真和测试,得出电机最优控制方法,实现了电机转速的高稳定性,为卫星姿态测量与控制的高精度提供了技术保证。According to the function theory of brushless DC motor, because of the special demand of motor＇s velocity stability in the measurement and control of the satellite attitude by infrared earth sensor, the mathematical model was developed. The motor speed and the system of motor drive were designed. By means of research analysis simulation and measurement, the optimization control method was designed and the high velocity stability of motor was realized. The results from above can be used to assure precision for satellite attitude measurement and control.
