摘　　要：设计了一种基于ARM的直流电机数字式电子调速器。本设计采用H桥电机驱动电路,光电编码器作为传感器检测电机的转速,以K60作为控制器,采用PI控制算法,利用PWM控制方案驱动H桥电路。控制器完成与上位机的通讯,实时检测控制效果。实验结果显示,本设计能实时调控电机转速,具有超调量小,调整时间短,无转速静态误差的特点。This paper designs a DC motor digital electronic governor based on ARM. This design uses H-bridge motor driver circuit. The photoelectric encoder is used as sensor to detect the speed of motor. As the main control module,K60 achieves communication with upper computer,at the same time it controls H-bridge drive circuit by using PWM control scheme. The algorithm part of this design adopts PID regulator. The experimental results show that the design is capable of controlling the motor speed in real time and has the advantages of small overshoot,short adjusting time and no speed static error.
