基于FPGA实现的步进电机细分控制信号发生器的设计

A Design of Stepping Motor Subdivision Control Signal Generator Based on FPGA

提出一种采用FPGA可编程芯片实现的步进电机转角的任意细分控制方法.介绍了在一片EPF 10K 10LC 84-4芯片内用VHDL语言编程实现了步进电机十六细分控制器的PWM模块、速度控制模块、数字比较模块等功能,该系统无需外接D/A转换器,结构简单,控制精度高,具有广泛的应用前景.

One new method of the angle revolving of stepping motor to subdivide the control is implemented by using FPGA （field programmable Gate Array） programmable chip and the VHDL （Very High Speed Integrated circuit Hardware Description Language） language. It was introduced that in a piece of EPF10K10LC84-4 chip,the stepping motor sixteen subdivision controllers about the PWM module, the speed control module, digital comparison module and so on have been achieved with VHDL language programming. The system need not link an exterior D/A converter. It has the characteristics of structure succinctness, high precision control and the widespread application prospect.
