基于CAN和TMS320F2812的永磁同步电机控制器的研究

PMSM Servo System Based on CAN Bus and TMS320F2812

基于永磁同步电机的矢量控制理论、CAN总线和TMS320F2812,从硬件和软件提出了一种伺服控制器的设计方案及实施方法,并自定义了电机控制的指令格式,给出了具体的实施过程.实验表明:在这种设计架构下的伺服控制器能取得较好的效果.

Permanent Magnet Synchronous Motor （PMSM） is characterized by its robust performance. However, it is difficult to control due to its non-linear, strong coupling and other factors. Controller Area Network （CAN） features in stability, high-speed and real-time, so it is suitable for real time control. This article provides hardware and software solution for PMSM servo system based on transvector control, in which the CAN bus and TMS320F2812.A new motor control code are defined, and the implementation scheme is also given. Experiment results show that the servo controller meets the desired technical requirements.
