Abstract

A kind of DC motor speed regulating system based on AT89C2051 single-chip computer is introduced in this paper.Taking a small-type of DC motor as the control object,PWM signal which is controlled and generated by AT89C2051 single-chip computer is used to drive DC motor by power amplifier.The acceleration and deceleration control of DC motor is finished by buttons.The open-loop speed regulating system is cheap and very easy to realize.It is stable and reliable in light-load system.
