Desenvolvimento de kits didáticos para controle de posição de motor CC

Abstract

This work deals with developing a prototype of educational kits for use in the Control Systems classrooms of the Electrical Engineering course in the UTFPR - Medianeira campus. The motivation for this work is to improve the students’ practical understanding, and the concepts learned in theory, specifically, how to perform a PID control of a process from a script written by the professor, utilizing a supervisory system based on the Modbus protocol. Initially, a literature review is made on state of the art regarding control systems and an evaluation of the main educational kits commercially available. The process to be controlled consists of a small DC motor with a potentiometer coupled to the motor shaft to acquire the position. A PIC 18F4550 microcontroller is responsible for generating the control signal for the motor and communicating with the supervisory system. The prototype was built and tested using tools available in the campus, presenting satisfying results through a PID controller. Furthermore, a user’s manual and a lab script for use in the classroom were written.
