Embedded System of DC Motor Speed Control Based on ARM

摘要

This paper designed a DC motor speed control system. The controller is ARM S3C2410, and the operating system is μC/OS-II, a real time operating system. Designed a closed loop system of motor speed control, adopted the algorithm of PWM to control the armature voltage, and motor speed is controlled by regulating, of armature voltage. The system has a good respondence.
