Soluções HILS baseadas em FOSS para treinamento e supervisão em controle de processos industriais

This work demonstrates a simulation environment, based on Hardware-in-the-Loop (HIL) technique, designed for utilization as an operator training tool and with potentiality, at a supervisory level, for analyzing security and optimization techniques. The environment, based on Java language and Eclipse compiler, a Free Open Source Software - FOSS, has no restrictions to their utilization. The digital environment simulates an industrial plant, but utilizes a built-in system composed of a command unite, in this case an analogical PID, and an industrial inverter, produced by WEG. It was necessary to design a specific communication board, whose main component is a PIC 16F877A, to connect the PID controller and the industrial inverter to the computer environment. The system simulates a real control plant belonging to the Laboratory of Industrial Process Control of the Engineering College of UFJF. Incorporating the nonlinearities and complexities of the real plant, and running with the same time constants, the HIL developed, totally FOSS based, allows the training of operators, optimization and safety analysis of the industrial plant.
