Closed loop speed control of dc motor using PID controller

Abstract

The development in technology has increased the demand of industries in present time. In this project the controlling speed of dc motor is done using Proportional Integral (PI) controller. The speed controller is a very important aspect, which is commonly used. PI has been used as a main aspect for controlling the speed. In this paper the input of the motor is changed so as to change the duty cycle of motor. IR sensor is used for sensing and then actual speed is displayed on LCD connected on arduino. Then reference speed is given by the potentiometer to the arduino then it will change the duty cycle and speed is varied.
