Level Process Control with Different Tank Configura-tions : Hardware-in-the-Loop Technique.

Abstract

This article presents a virtual laboratory of industrial processes focused on level variable, where non-linear MIMO advanced control algorithms are im-plemented based on the determined mathematical model, using Hardware-in-the-Loop simulation technique. An immersive and interactive virtual environment is presented in the Unity 3D graphic engine, where different tank configurations are shown for the monitoring, visualization and control of the process control states, which consequently brings the user closer to the industrial field in a dynamic approach, in addition, virtual reality is used as a tool for facilitating the teaching and learning about control. Thus, a low-cost solution is provided to evaluate con-trol algorithms; in addition, simulation results for each controller are included, as well as the stability and robustness analysis of the system. Hardware-in-the-Loop technique and virtual environment allow to observe the behavior of control errors in a level process, finally it is determined that advanced controllers provide greater efficiency than conventional control techniques.
