Abstract

In this study, an educational tool was prepared for a direct current (DC) motor, proportional (P), integrated (I) and derivative (D) speed controller with a shorter term and more economic education of the control systems. Parallel with the improvements of industrial technology, the development of computer and control technology has magnified the importance of either the theoretical or practical education of the motor speed control. The education of motors speed control in laboratory is very important, but this education is usually difficult because of a lot of abstract equations, difficult motor dynamic models and PID parameters. To overcome the mentioned negativities, an education tool was prepared for the education of DC motor speed control with PID controller. The tool which was prepared on C# environment has a flexible structure and a graphical interface. It has enabled the analysis of working principles of the P, PI, PD and PID control and traceability of the system response by the help of graphics, under different conditions created by changing the values of PID parameters. Besides, the motor could control the motor speed and reference speed and the changed PID parameters can be observed in the distance space over the internet.

Key words: DC motor speed control, PID control, educational tool, PIC16F877, motor control over the internet.
