Microcontroller Based DC Motor Speed Control System Design

本文介绍了一种基于AT89C52单片机的直流电机调速系统设计。本系统以AT89C52芯片为主控,利用PWM调制技术,完成直流电机的转速快慢、正反转调节,并通过LED数码显示管将转速脉冲计数显示出来。利用Proteus软件仿真调速,测试结果表明:电机的转速能通过按键进行调节,也能够较好地控制转速精度和动态响应范围。同时,它在社会各领域中有着较广泛的实际运用。

In this paper, a DC motor speed control system based on single chip microcomputer is introduced. The system takes AT89C51 single chip computer as the core, the speed and direction regulation of DC motor is accomplished by PWM modulation technology. The speed pulse counter is displayed by LED digital tube. Using Proteus software simulation speed, the test results show that： the speed of the motor can be adjusted by the key, and better control the speed accuracy and dynamic response range. The system has a very wide range of applications In reality.
