摘要
系统基于51单片机控制,以FPGA芯片来实现驱动,步进电机的脉冲分配作为核心电路加以必要的数字模拟辅助电路,形成一个4相8拍步进电机定位控制系统。该系统完成了步进电机的正确脉冲分配并实现了步进电机的方向调节、速度调节及定位控制等功能,由于单片机控制模块的使用使得FPGA驱动模块对步进电机的定位控制更加方便,对步进电机的速度控制精度很高,并且更加准确。
A 4-phase 8-step stepper motor positioning control system is established based on 51 MCU, whose driver is achieved by adopting FPGA, and pulse allocating of stepper motor is used as kernel circuit supported with necessary digital analog circuit. This system can implement smoothly correct pulse allocating and can adjust the direction of stepper motor, speed and position, etc. Using the MCU control, the FPGA driven module can advance speed control accuracy.
