基于AVR单片机的步进电机控制器设计 (毕业论文)

基于AVR单片机的步进电机控制器设计:介绍了步进电动机的发展史,及国内的现状和步进电动机未来的应用前景。并且阐述了步进电动机转速、角度、转矩的控制原理。本文阐述了一种步进电机控制器的设计方案，并绘制了原理图和PCB板图，撰写了程序源代码。实现了对步进电动机转速、角度的控制，并完成了实物的制作。这期间主要使用protel99se软件绘制原理图和制板，使用proteus7.1软件进行程序代码的仿真和功能的理论验证。最后通过硬件的调试验证程序代码的实际功能，完成对控制器的设计。

Abstract

IntroducTIon step enter electric motor of development history, and local present condiTIon and step enter electric motor future of applicaTIon foreground.And elaborated a step to enter electric motor to turn soon, angle, turn Ju of control principle.This text elaborated a kind of step enter electrical engineering controller of design project, and drew principle diagram and PCB plank diagram, composed a procedure source a code.RealizaTIon to step enter the electric motor turn soon, angle of control, and completion real object of creation.This period main usage the protel 99 se the software draw principle diagram and make plank, usage proteus 7.1 softwares carry on an imitate of procedure code true with the theories of the function verification.The end experiment certificate procedure a code through an adjust of hardware of actual function, completion design controller.
