Diseño e implementación de una planta didáctica industrial con aplicaciones para el control de nivel en un reservorio, para el laboratorio de automatización industrial

Abstract

This paper called "Design and implementation of an industrial plant with applications for the control of the level in a reservoir for the industrial automation laboratory" aims to provide a learning tool that allows the simulation of industrial processes through didactic plants for students of the study program of Electronic Engineering, of the Universidad Politécnica Salesiana. The didactic plant has a level control. Implemented with type ultrasonic level sensors, float, capacitive; and output elements such as solenoid valve, variable speed pump, piping accessories with fast connection, which can be manipulated by a control module with a PLC Siemens S7-1200 connected via the DB-25 port to the board that is part of plant. The proper functioning of the project was based on the analysis with experiments and tests focused on closed loop PID control of final control elements. It has succeeded in demonstrating that by optimization technique Ziegler & Nichols (practical method) a starting point to select data from the proportional, integral and derivative variables with a close at the end controller criterion left parameterized has been found in the PLC. The plant with its own operating practices provide students the opportunity to become familiar with equipment, components, systems and control variables that are used in industries, being a contribution to the subjects matters of Industrial Automation.
