Plataforma didática hardware-in-the-loop para emulação de sistemas lineares

Abstract

In the field of engineering and exact sciences, there is a constant demand for experimental verification of control strategies, modulation schemes, among other aspects. Process control projects and tests are difficult tasks that can discourage students from working in the field due to the steep learning curve. Modern approaches to control systems education use simulations and experiments to facilitate the learning process. However, environments such as university labs do not have the high financial resources needed to purchase these solutions. The need versus the difficulty of acquisition motivated the creation of a low-cost HIL platform for simulating generic linear systems capable of performing the same or at least the main functions of commercial equivalents. This work presents the stages of design, simulation, and experimental tests of hardware and software implemented in microcontrollers, for the generic implementation of up to second-order systems. Likewise, the final assembly steps of the electronic product developed and the experimental validation with a computer of the mathematical models simulated in discrete-time and sending the data to the system to be simulated are also explored. After demonstrating the validations, the results obtained are discussed.
