Implementación de un Sistema Hardware-in-the-Loop (HIL) en una Planta de Nivel con Control PID Monitoreado Mediante IoT

Abstract

This study presents the design and implementation of a Hardware-in-the-Loop (HIL) system for liquid level control using a PID controller with real-time monitoring via the Internet of Things (IoT). A simulation model replicating the dynamic behavior of a physical plant was developed, allowing performance optimization of the PID controller prior to deployment in real industrial environments. The controller was tuned using the LAMBDA method, enabling a stable response with no significant overshoot. The IoT integration facilitated remote supervision and adjustment of the system, reducing operating costs and enhancing process efficiency. The obtained results demonstrate that the HIL approach improves control precision, reduces response time, and enables safer evaluation of advanced control strategies.
