基于单片机的步进电机控制系统 摘要步进电机是一种通过电磁脉冲信号控制相绕组电流实现定角转动的机电元件,其有易于开环精确控制、无累积误差等特点,在各个领域中获得了广泛的应用。目前步进电机控制技术已经比较成熟,在高校教学中也越来越得到重视。有感于目前高校步进电机实验系统通常过于复杂昂贵,很难有效地使学生了解步进电机的控制方法并且亲自动手完成实验,因此本文讨论的内容就是一套硬件系统比较简单、经济,但功能齐全、适应性强、操作方便,能够把数字电路、模拟电路、单片机技术、电机控制技术结合起来的步进电机教学实验系统。本文首先描述了步进电机的进展应用情况,以及常见的控制方式。然后以单片机为主控制器设计了一整套的控制方案,以及完整的程序流程以及设计。 关键词:步进电机 单片机 教学平台 控制方式 The Stepping Motor Control System Based on SCMAbstract:Stepping motor is a kind of component using electric pulse signal to control winding elements to realize angular displacement. It is easy to realize accurate control, no accumulated error an so on. Thus, it is got extensive application. Stepper motor control technology has now more mature.And it more and more taken seriously in teaching in college. Feeling the stepper motor test system in college are usually too expensive and complicated. It is difficult to make students understand the principle of stepper motor and fulfill the experiment. Therefore, the contents of this paper is design a simple step motor control system, which has complete function, strong adaptability, easy to operate, high dependability, missing electronic technique, SCM technique and motor control technique. This paper describes the stepper motor application development, and common control first. Then, using SCM as a main controller to put forward the whole system, and the complete process flow and design.Key words: Stepping Motor,SCM, Education Platform, Control目录1.1 步进电机的应用及进展前景...........
