Nowadays the industrial field is testing more robust controllers to deal better with complex control processes, to guarantee high reliability and efficiency. In this context, this work aims to present the design of a Fuzzy Controller embedded in an Arduino Mega microcontroller, taking 2 experimental didactic plants into consideration: A resistor-capacitor circuit and a direct current motor assembly. Then, the Fuzzy Controller will have its effectiveness and also be compared with other topology: The parallel PID controller. In addition, an interesting study is done when the storage capacity of routines in the Arduino board is considered, regarding the dynamic memory when new membership functions and rules are increased. The Fuzzy controller was embedded obtaining satisfactory results when compared to the PID controller, taking non-intrusive performance indices as validation parameters.
