全数字交流主轴伺服驱动器的设计

摘要

The highperformance digital AC spindle servo drive system was designed,which used DSP as control unit and advanced IPM to constitute VSI. The slip frequency vector control has been implemented and complete protection circuit has been designed. The experiments and application results showed that the system had good performance.%设计一种全数字交流主轴伺服驱动器.该系统以高性能数字信号处理单元为控制电路核心,采用先进的智能功率模块IPM( PM150RLA120)作为功率开关元件组成逆变器.采用转差频率式矢量控制,并设计了较为完善的检测与保护电路.实验结果表明,该系统具有良好的静态和动态性能.
