Módulo didático portátil baseado do controle de temperatura de um sensor NTC

Abstract

Didactic modules are important to consolidate fundamental concepts as well as to prepare and to develop key abilities required to design and implement closed-loop control techniques. From experimental tests, practical aspects such as noise attenuation, constraints effect mitigation, robustness and non-linearities can be characterized. In this work, the NTC (Negative Coefficient Temperature) temperature control is presented from a low cost perspective in the context of control engineering education. This kind of didactic module can be highlighted due to the combination of low cost and portability with an expressive non-linearity. Hence a brief systematic discussion is presented based on the phenomenological model, the materials and methods, and some experimental results for providing emphasis on ingredients such as the portability, low-cost requirement, and on the non-linear property.
