CHAPTER I INTRODUCTION

1.1 Introduction

Control system is a system or a device or set of device to manage, conduct command, order and direct or regulate the behaviors of the other device or one system. With it we can control or change the speed of the motor to our own desired one. The controllers that can be used are Ideal Integration Compensator PI, Ideal Derivative Compensator PD and Ideal Integration-plus-Derivative Compensator PID. So, this proposed project is about to develop a graphical user interface GUI of these controllers for controlling the speed of the motor. Means user can control the motor’s speed via Personal Computer PC. The development of GUI will be implementing using Microsoft Visual Basic 6 VB6 software. This produced system will incorporate interactive and graphical for convenience and user-friendly.

1.2 Problem Statements

Proportional integral derivative PID control is the most commonly used control algorithm in the industry today. PID controller popularity can be attributed to the controller’s effectiveness in a wide range of operation conditions, its functional simplicity, and the ease with which engineers can implement it using current computer technology. Besides, it give confusion for lecturer and student, who are implementing and study the PID controller in control system because of the concepts of controller are abstract and difficult to fully comprehend. For more understanding purpose, it is advantageous to learn and apply the PID controller effectively through empirical study. Dc motor speed control using simulation PID controller is a good application that can help students to understand the characteristic of the PID controller in control system. These equipments are a direct application that can visualize the theoretical in real time.

1.3 Objectives

Regarding this project, there are precise objectives to be accomplished. In completing this project, objectives are the basic in selection or designing base in order to provide a means in organizing efforts toward accomplishment those objectives. 1. To develop simulation system of PI, PD and PID controller using VB6 software. 2. To develop interfacing interacts between hardware and software. 3. To study the effect of applying PI, PD and PID controller to the Motor System; speed. 4. To differentiate between PI, PD and PID controller through the result obtained.
