    DC Motor Speed Control Using a Fuzzy Logic Controller
    (University of Management and Technology, 2013) Zafar, Arslan; Janjua, Aneeq Suhail; Hussain, Irfan Mureed
    The objective of this report focuses primarily on the design and implementation of DC motor speed control using Fuzzy Logic and provides a brief description about speed control of a DC motor. There are different methods of speed control but we have found that fuzzy control to be the most appropriate/suitable for our project. First of all, in no load condition, the DC motor shall run at its full speed and the speed of the motor shall then be varied and adjusted via a dimmer (variable resistor) and set to a specific number based on revolutions per minute. The speed of the motor will be displayed on an LCD and then a PWM signal shall be generated from the controller and the motor speed shall change. Now if we switch on an electrical load at this speed, the motor speed shall decrease. Fuzzy logic, implemented via an AVR microcontroller, shall then be applied to maintain the previous desired speed. We (group members) have tried our level best to fulfill all the requirements of this project. This report has been written in such a way that it is easy for anyone with basic knowledge in Engineering to interpret and understand it. It all depends upon the reader now to deduce it carefully and to comprehend what we wish to express.
