基于DSP的交流伺服系统

DSP-Based AC Servo System

推导出永磁同步电动机（ＰＭ电机）的数学模型。根据交流电动机矢量控制理论，提出了ＰＭ电动机交流伺服系统控制结构，并实现了以ＤＳＰ为控制器，ＩＧＢＴ为功率开关器件的永磁同步电动机矢量控制转矩闭环系统。最后给出了实验结果。

The mode of PM motor is derived. A control structure of PM motor AC servo system is put forward on the basis of vector control theory. The torque dose-loop vector control system, in which DSP is used as controller and IGBT is used as power switch component, is completed for PM motor. Finally experimental results are presented .
