基于FPGA的多轴永磁同步电机驱动控制系统设计与实现

Design and Implementation of Multi-axis Drive and Control System Based on FPGA

针对多个永磁同步电机一体化驱动控制的需求,开发了一种以FPGA和智能功率模块为基础的控制驱动系统,包括绝对编码器读取、电流读取、矢量控制和PWM波发生等模块,并在NIOS II软核中编制了相关的控制程序,可以实现同时对4个永磁同步电机的闭环控制。进一步对系统的执行时间和电流环、速度环控制进行了实验验证,证明了系统的实用性和高效性。

In this paper, for multiple PMSMs drive and control, an integral scheme based on FPGA and intelli- gent power module is proposed. Absolute encoder reading, current reading, vector control and PWM generating com- ponents are developed. NIOS II is used to implement the four PMSMs control algorithm. Experiments on execution time, current loop and speed loop tests demonstrate the effectiveness and efficiency of the proposed system.
