Real Time Speed and Position Control of DC Motor with PID and Fuzzy Logic

Abstract

With the increasing technology, different types of motors have been widely used in many different fields in recent years: Especially due to the increase in industrial applications, the use of motors with many different features has increased significantly in different fields. In this context, Direct Current (DC) motor is one of the most preferred and used motor types. With the rapid development of power electronics and microelectronics technology, the brushless DC motor usage area has expanded considerably. Brushless DC motor has many advantages such as small volume, light weight, high efficiency, energy saving, easy speed adjustment, simple structure, reliable operation and easy maintenance. Nowadays, since brushless DC motor is widely used in industrial control processes, DC motor control has become an important problem.

In this study, it is aimed to develop a system for position and speed control of a Direct Current (DC) motor. Although there are various control methods for DC motor position and speed in the literature, PID control algorithm and Fuzzy Logic are used in this project. The system consists of two main parts. These are; the software part where the information is received and processed and the electronic circuit part that works on the basis of this software. The software part was realized in MATLAB environment. The written codes were tested on the system in real time with the control card and the system was tested on the system. A rule table was created for the system in order to use membership functions in fuzzy logic operation. The change of the error in the created rule table was observed. In addition, PID control application was realized on the system and the results of overshoot, rise time, settling time and steady state errors were observed.

As a result of the project work, the position and speed control of the DC motor, which is one of the widely used motor types in industrial applications, has been realized in real time. It is considered to have a very important place in terms of both academic and industrial projects, since the work is a very important circuit equipment in the industrial sector and the work is tested in real time and high success is achieved. Especially motor control, which is one of the indispensable and most important parameters of the automation sector, shows that it is a

potential study that allows application in the industry in this field.
