Abstract

This paper describes the speed control of dc motor using back emf method. Among the various techniques for controlling the speed control of dc motor, this method offers relatively simple and cost effective solution. In this method no feedback sensor or extra feedback signal processing circuitry is required. The speed control of dc motor has been achieved using pid controller which is implemented on PIC microcontroller and one method is also proposed to achieve better speed control of dc motor.
