The Design of Speed Regulation System Based on DC Motor

Chunyan Jiang

Abstract

Aimed at the problems existed in the mechanical hydraulic governor in our country,its electronic part was improved in order to control the speed expediently.The direct-current motor has large starting torque,small volume,light weight,high efficiency and easy speed-control.According to the theory of automatic control,the double closed loop DC PWM speed regulation system was designed by using PWM control method to control the speed of direct-current motor effectively.This speed-tuning system could be applied to mechanical hydraulic governor to complete its technical improvement.
