Uma plataforma educacional de baixo custo baseada no sistema barra e bola para o estudo de desempenho de sistemas dinâmicos

Abstract

Since the end of the last century, technology has evolved rapidly causing changes in society. Transformations in health, economics and communication are examples of these changes and the area of education is one of the fields that suffers the most positive influences from the use of technology. Thus, this work presents the development of a low-cost educational platform based on the bar and ball system for teaching the discipline of control of dynamic systems to be allocated in the control laboratory of the Federal Institute of Amazonas (IFAM), where students can study the performance of dynamic systems and prove concepts seen in the classroom, avoiding the abstraction caused by classroom theory. It is well known that the teaching of engineering based exclusively on speeches passes on a very incomplete and not very instigating idea, which generates disapproval and disinterest on the part of the students. Currently, there is no educational platform at the Federal Institute of Amazonas aimed at teaching the control discipline as developed in this work. Therefore, an educational platform was developed to be used exclusively by IFAM teachers and students, filling the lack of a technology that combines the theory seen in classrooms and operational practice. The lack of this type of tool, in a technology teaching site, is a flaw that must be remedied in order to improve the campus teaching process and instigate research to be carried out in the area that highlight the IFAM’s name. Therefore, a modeling of the bar and ball system, bibliographic review of the PID controller with implementation through the Arduino platform, development of a graphical interface to control the bar and ball plant through the software in Labview, in addition to the simulation and analysis of the plant in Matlab software in order to graphically present the system performance and the possible gains of the controller through the Matlab control toolbox and systems.
