Monitoring of a level control system in a pilot plant, using supervision developed in the ScadaBR software

Abstract

Industry 4.0, a concept that emerged in Germany in 2011, has been increasingly prominent on the international stage, but its implementation in Brazil has been slower. The main objective is to develop a functional supervisory system in ScadaBR, connected to the Arduino Uno, to monitor and control a pilot plant for level control, both in open-loop and closed-loop with PI controllers. A pilot plant consisting of a liquid reservoir, pump, ultrasonic sensor, and Arduino Uno was used, and steps were taken for level measurement, connection to ScadaBR, pump activation, and implementation of two PI controllers. Tests were conducted in open-loop and closed-loop configurations, with better performance observed in closed-loop tests using a PI controller proposed by Pitta et al. (2023) compared to another PI controller developed by Almeida et al. (2021). The developed supervisory system proved effective in real-time data collection and control strategy implementation. The study's objectives were successfully achieved, and for future work, the integration of other devices and the application of machine learning techniques to improve control system performance are suggested.
