摘要
随着我国经济的高速发展,微电子技术、计算机技术和自动控制技术也得到了迅速发展,直流电机调速技术已经进入一个崭新的时代,其应用越来越广。而作为控制核心的各种单片机芯片也在不断的更新发展,其功能越来越强大。随着人们对其要求的提高,直流电机控制系统的调速方法也相应的产生了PWM(脉宽调制技术),其控制芯片也由原来常用的51单片机系列升华为ARM系列的控制实验板。本设计基于ARM9开发板的直流电机控制系统的调速,以显示ARM开发板的独特功能,利用脉宽调制技术,调节占空比以达到调节转速的目的,将测得的数据传给上位机后进行观测。设计大体上分为硬件设计和软件设计两部分,硬件部分包括驱动模块,控制模块,数据检测模块以及通信模块,软件部分包括程序设计,两大部分实现了对电机转速的监测和控制,更好的确保了设计的准确性。通过合理的选择和设计提高了直流电机控制系统调速的技术,学习和研究新型控制芯片,使设计达到了较为理想的控制效果是本设计的宗旨。

Abstract
Along with the rapid development of Chinese economy, microelectronics technology, computer technology and automatic control technology is rapidly developing, dc motor control technology has entered a new era, the more and more wide application. As the core of MCU control chip are constantly updated development, its function and more for the people, the control system of dc motor control method and the corresponding produce the pulse width modulation (PWM) and its control chip technology is used by the original sublimated 51-series puter series of control board ARM series. The design is based on ARM9 development board of the control system of dc motor speed, in order to show the ARM development board, using the unique function of PWM technology, SHCH adjustment in order to achieve the goal, will adjust speed measurement data to PC and software it. General design of hardware design and software design is divided into two parts, hardware part includes driver module, control module, munication module, and the software module includes programming module, two most of the monitoring and control motor speed, better ensure the accuracy of the the reasonable selection and design of dc motor control system to improve the speed of technology, learning and research, new control chip design to the ideal control effect is the design purpose.
