基于STC89C52单片机的步进电机控制系统设计(开题报告,外文翻译,论文9000字)
摘要
作为机电一体化产品中重要成员的步进电机，是一种具有良好功能的执行性的原件，由于计算机的普及和应用、电子的发展以及自动化技术在日常生活领域的发展和输入，使得步进电机的市场越来越广大。随着工业技术的不断发展，以及同类产品的不断出现，步进电机正面临着前所未有的挑战，如何实现对步进电机的有效控制，是电子设计及控制领域一项普遍关注的课题。
本论文主要完成的设计内容是通过软件编程设计及硬件搭建完成对步进电机的控制，实现其正转反转加速减速停止功能。所做的工作分为三部分：首先在第一章绪言部分介绍步进电机的理论知识，然后再介绍步进电机工作的原理，再者详细介绍下本步进电机控制系统设计的核心部分：STC89C52单片机、28BYJ-48步进动机、ULN2003驱动芯片计。最后用相应软件编程驱动步进电机，使其完成正转、反转、及加减速的功能。

The design of stepper motor control system based on single-chip
Abstract
The stepper motor is not only the key part of motor integration, but also a digital actuator which has good property. With the popularity and development of computer application technology, electronic technology and automation technology into all fields of the national economy, the demand for the stepper motor is increasing. As industrial technology develops constantly and similar products are emerging, the stepper motor is faced with unprecedented challenges. And how to attain the effective control of the stepper motor is a topic which arouses common attention of the field of electronic design and control. [资料来源：http://www.doc163.com]
This paper puts forward arousing software programming and hardware structures to attain the control of the stepper motor for realizing the functions of its rotation, reversion, acceleration, deceleration and suspension which can be split into three parts. It introduces the stepper motor at first. Then it tells the primary principle and technical characteristics of the control system of the stepper motor. For further discussed at last are the control system design which has scmSTC89C52, motor28BYJ-48 and driver chipULN2003 as the core, and how to use the software to realize the function of its rotation, reversion, acceleration and deceleration.
