基于QT的步进电机加速曲线生成工具的研究与实现

摘要

随着市面上越来越多步进电机驱动器的推广,使得步进电机的操控和使用越来越方便,但是在某些场合下需要步进电机运行在高速状态下,为了防止步进电机的失步、过冲、堵转现象,需要合理设计其加减速过程.从步进电机的物理特性出发,研究了步进电机的加速过程,并开发出一款步进电机加速曲线生成工具软件,该工具软件可以根据设定的步进电机参数和加速过程需求参数自动地生成加速曲线数据,并且可以方便地导出成.C和.H文件供单片机程序调试和使用,最后通过单片机控制平台验证了其有效性与实用性.%With the promotion of more and more stepper motor drivers on market,it is convenient to control and use stepper motors.In some cases the stepper motor needs running at high speed,and in order to prevent the loss of step,overshoot and stall,its acceleration and deceleration process need to be rationally designed.The theory of the acceleration process of stepper motor is studied based on the physical properties of the stepper motor and then the stepper motor acceleration curve generation tool software designed.This tool software can generate acceleration curve data automatically according to the stepper motor parameters and acceleration process demand parameters,and can be easily exported to.C and.H file for microcontrollers program debugging and using,and finally through the microcontroller control platform its effectiveness and practicability is verified.
