Integración MATLAB/Simulink para identificación y control multivariable de una planta de fluidos didáctica

Abstract

This project aims to upgrade a fluid handling plant with new sensors and actuators to enable communication with MATLAB. This new design seeks to completely replace the previous one, whose main problem was its inability to communicate with MATLAB, rendering it unusable for experimental applications. The new plant will benefit students by allowing them to apply new knowledge in this type of environment. To carry out this project, the ESP-32 microcontroller was used along with new pressure sensors and actuators, such as a proportional valve. An optimized serial communication protocol was implemented for the simultaneous sending and receiving of data. The results showed very stable bidirectional communication between the microcontroller and MATLAB, enabling the generation of level graphs for each tank. The operational response of the electronic components to commands from MATLAB was also validated. It was concluded that the upgraded plant constitutes a new experimental platform for real-time process analysis. Keywords: ESP-32, Communication, Level, MATLAB, Process
