Use of operational amplifiers and discrete off-the-shelf components to teach fuzzy logic controller concepts

This paper presents the realization of Fuzzy Logic Controller concepts using operational amplifiers as a tool to teach students about design and modeling. Design of a FLC is performed because this path provides a good background for the student to experience a complete process approach that goes from verbal description of a problem throughout the final practical implementation, passing through the process of mathematical modeling and the understanding of what a realization of a function means. All the basic blocks consist of operational amplifier circuits that are taught in a first circuit course, just pushing the application a little beyond but still within the reach of the already acquired background.
