基于ARM的直流电机调速系统的设计

Design of the speed regulation system of DC motor based on ARM technology

在现代数字类控制中,对各类电机速度的控制成为一个重要的研究课题.对应用于ARM嵌入式系统中的直流电机的调速问题进行研究.通过方案对比,选择PWM脉宽调制为主要技术方案,针对该方案进行了简要论述,并给出系统的软件流程,可实现ARM嵌入式系统对直流电机正转、反转以及速度的控制.

The speed control of all kinds of motor has become an important issue in the modern digital control. This paper studied the problem of the speed regulation system of DC motor based on ARM technology. Through the comparison of different schemes, the PWM pulse is chosen to be the main technical solution, about which the paper briefly discusses the scheme. Meantime, the design of system software process is illustrated in order to achieve the DC motors forward and reversal and speed regulation of the ARM embedded system.
