Desarrollo del control electrónico del módulo didáctico de nivel y caudal para el laboratorio de electrónica de la UPS.

Abstract

The tank system module belonging to the Electronic Engineering Career Control Laboratory of the Universidad Polytechnic Salesian campus Sur in Quito, tries to solve academic purposes in automation that allow to control variables of liquid level and flow. In the present project, three control algorithms implemented, such as: P, PID and Fuzzy, for the use of the level and flow variables controlled by servo valve, flow sensor, level sensor and the centrifugal pump by means of the frequency inverter in the tank system. First, the explanation of each component that intervenes in the tank system for level and flow was carried out together with the appropriate selection of materials that meet the operating needs. In addition, the flow diagrams for the implemented algorithms and the diagram of the elements of the control board were elaborated. Then the programming of the microcontroller and HMI screen carried out, continuing with the connection of the electronic elements during the implementation. Finally, its operation verified through tests of each algorithm recording the results in the written work. It was concluded that the variables level and flow must have synchronization for each control process.º
