Abstract
There are several high-performance commercial resources for implementing simulations with emulated plants, the so-called hardware-in-the-loop control system, but often inaccessible to most users due to the high costs involved. The objective of this work is to propose a low-cost platform and a methodology for implementing hardware-in-the-loop systems through the electronic prototyping platforms Arduino UNO and ESP32, with parameterization via IoT. The motivation for remote parameterization is to make it possible to redesign the controller and download its parameters even in places with difficult access. To illustrate the methodology, a PID controller was implemented in an ESP32 and connect to a second order dynamic plant emulated in Arduino Uno by means of the A/D and D/A converters of the platforms. The proposed methodology is based on the real-time implementation of differential equations by simulating the integrators of their representation in the state space and making use of hardware interrupts. The results obtained were compared with numerical simulations and indicate that the method can be used in different real applications
