摘　　要：设计了一种基于DSP及轴角数字转换器AD2S80A的高精度无刷直流电动机控制系统,实现了电机转子位置的精确定位,同时为电机换相提供了准确的位置参考,提出了一种新的消除无刷直流电动机转矩脉动的补偿策略。系统集成度高,控制灵活,稳定性好。实验结果表明,该系统运行良好,转矩脉动已基本消除。Brushless DC motor control system with high precision based on DSP and AD2S80A - resolver - to - angel digital converter was designed. This system realized the exact fix of rotor position. It provided the accurate position for motor commutation. A new method was given to eliminate the brushless DC motor torque ripple. The whole system hosts high integration, flexible control and strong reliability. Experiment results indicated that the system had a high performance, and the torque ripple was eliminated completely.
