Speed Control of DC Motor Using Microcontroller

Authors(2) :-Katke S P, Rangdal S.M

Direct current (DC) motor has already become an important drive configuration for many applications across a wide range of powers and speeds. The ease of control and excellent performance of the DC motors will ensure that the number of applications using them will continue grow in future. This paper is mainly concerned on DC motor speed control system by using microcontroller PIC 16F877A. It is a closed-loop control system, where optical encoder (built in this project) is coupled to the motor shaft to provide the feedback speed signal to controller. Pulse Width Modulation (PWM) technique is used where its signal is generated in microcontroller. The PWM signal will send to motor driver to vary the voltage supply to motor to maintain at constant speed. Through this paper, it can be concluded that microcontroller PIC 16F877A can control motor speed at desired speed although there is a variation of load.
