Diseño de un control difuso tipo Mamdani para regular la temperatura de una Acuario tipo tropical

Abstract

In the present research work, an automatic control technique based on fuzzy logic is shown to regulate the temperature conditions in a tropical aquarium with a capacity of 100 liters. To analyze the effectiveness of the technique, the design and implementation of a fuzzy logic controller type Mamdani was carried out. Subsequently, the diffuse controller was integrated into an electrical system using a 100-watt resistor. The regulation is carried out from the acquisition of the water temperature, thus varying the current of the resistance, a temperature sensor, and a heater as actuators were used. The functionality of the system is verified through the Artix-7 FPGA platform, using the VHDL hardware description language. The controller design was developed using the fuzzy logic tool in Matlab in order to compare experimental results of the FPGA, obtaining an error of 2.94% accuracy between both designs.
