基于ARM的直流电机模糊控制系统设计与研究

Design of DC Motor's Fuzzy Control System Based on ARM MPU

本文介绍了ARM嵌入式微处理器芯片的架构,直流电机的PWM控制,以及利用模糊算法建立直流电机控制系统。通过对直流电机同轴光学码盘的测速实现闭环反馈,在ARM嵌入式微处理器中调用模糊控制算法实现电机速度的控制。本课题着重介绍了模糊控制在嵌入式ARM微处理器中的实现,以及两者在直流电机控制中的优越表现。

In this article, it describes the structure of ARM MPU, the PWM control of DC motor, and uses the Fuzzy control arithmetic to build the DC motor control system. A closed loop feed back system can be build for using an optics coding machine, and transfer the Fuzzy control arithmetic to the ARM MPU, then control the motor＇ s speed exactly. This article emphases the carry out of Fuzzy control in the ARM MPU, and the ascendant performance of the two on DC control.
