基于单片机的电动机正反转控制设计
. .基于单片机的电动机正反转控制设计学生：xxx（指导教师：xxx）（xxxxxx电气信息工程学院）摘要：
基于单片机的基本理论，本文设计了一种步进电机控制系统。
该系统通过软硬件的设计调试，实现步进电机能根据设定的参数进行开关加减速控制，使控制系统以最短的时间到达控制终点，而又不发生失步的现象；
同时它能准确地控制步进电机的正反转，启动和停止。
硬件是以AT89C51单片机为核心的控制电路，主要包括：
开关输入电路、液晶显示电路、步进电机的驱动电路等。
软件部分采用C语言编程，主要包括液晶显示程序、步进电机的正反转即快慢程序等。
通过仿真验证了本文设计系统的实用性能。
