基于FPGA的步进电机控制器的开发与研究

Development and Research of Stepping Motor Controller Based on FPGA

步进电机广泛应用于各种需要精确定位的系统中,尤其是数控机床中。设计了一个基于FPGA的步进电机控制器。采用EDA技术模块化和自顶向下的设计方法,实现了步进电机启停、正反转控制、调速,且具有单双拍2种运行模式和能在LED上显示速度的功能。在软件平台Quartus II 6.0下,对设计进行编译、仿真,并下载到FPGA器件上验证其正确性。设计的控制器具有很好的移植性。

Stepping motors are widely used in all kinds of precise position systems, especially in CNC machine tools. A stepping motor controller based on FPGA is designed. Adopting the EDA design method of the modularity and top-down, stepping motors can start and stop, positive inversion control, speed control,have single and double shot two kinds of operation modes, and the function of playing speed in LED. In the software platform of QuartusII 6.0, the compile and simulation of the design are achieved, and it is downloaded to the FPGA device to verify its correctness. The controller has good transplantation.
