A We Platform for Learning Control System Based on IoT Application

Abstract

This work presents the development of an IoT application aimed for teaching process control, which allows remote access by web. It is a level control system with a friendly, responsive and interactive interface that allows the implementation of SISO type control systems (Single Input and Single Output) and can be accessed and controlled directly through mobile devices. The interface includes dashboards and graphics, real-time monitoring of the equipment image and adjustment of reference values for the control, which is computationally implemented through discrete PID (Proportional, Integral and Derivative) controllers. The work approaches the accomplishment of the following experiments: determination of the characteristic equation that relates the level with the measurement in the sensor, mathematical modelling of the continuous and discrete system and the implementation of several tuning techniques of PID controllers. The practical results obtained are validated by simulation and practical experiments demonstrating the efficiency of the implemented control system and the functionality of the solution. © American Society for Engineering Education, 2023.
