基于DSP的双闭环永磁同步电机控制系统设计

The Design of Drives System for PMSM Based on DSP

对永磁同步电机(PMSM)驱动控制系统进行了设计和实现,硬件采用TMS320F2812型DSP,整个电驱动控制系统包括电源模块、逆变模块、控制模块、驱动模块、转速、转子位置检测、RS232串口通讯模块等,软件采用矢量控制算法及空间矢量脉宽调制(SVPWM)予以实现,系统采用电流、转速双闭环结构,实现了高精度调速。

A motor drives system for PMSM is presented.The hardware is designed as centered the TMS320F2812 DSP, and the whole electrical drive system including power module, inverter module, control module, drive module, system security detect module, rotor position and speed detection module and RS232 serial port communication module etc.Based on the hardware,the software can realize the vector control and space vector pulse width modulation （SVPWM）.In order to ensure the quick response and high precision speed regulation, the control system is designed as speed and current dual closed loops.
