摘 要:通常无刷直流电机的控制系统是由纯电路制作而成的,但是纯电路的制作成本比较高,而且它在某些方面不能满足人们对智能化控制的要求。本文研究的是以单片机为核心的控制器,单片机体积小、稳定可靠的优点使得控制系统的灵活性比较高,而且单片机是可编程的,通过软件控制直流电机,可以更好的实现对直流电机的控制。无刷直流电动机有很好的动态和静态调速特性,其简单的结构、可靠的运行状态以及更加灵活的控制方式使得无刷电机在各个方面得到很大的普及。正是这些优点的存在,使得利用单片机控制直流电机的研究变得越来越有优势,同时也促进了直流电机的发展。27881 毕业论文关键词:无刷直流电机;闭环控制;单片机
Design of Brushless DC Motor Closed-loopController
Based on STC89C52 MCU
Abstract: Brushless DC motor control system usually is made of pure circuit, but production costs are higher than pure circuit, and in some ways it does not meet the requirements for intelligent control.This study is based on SCM as the core of the controller, single chip small size and flexibility advantages of stable and reliable control systems is relatively high, and is programmable via software control of DC motor, you can better control of DC motors. Brushless DC motor has good dynamic and static speed characteristics, its simplestructure, reliable operation and more flexible control mode makes the brushless motorwidely in all aspects. It is these advantages exist, makes the use of single-chip microcomputer control system of DC motor's research has become more and more advantages, but also promoted the development of DC motor.
