Object-oriented modeling of virtual laboratories for control education

Abstract

The combined use of Ejs, Matlab/Simulink and Dymola (with Modelica language) has been successfully applied to set up virtual labs for control education. The tasks completed to achieve this goal are discussed in this manuscript: (1) the development of a novel modeling methodology adequate for interactive simulation; (2) the object-oriented design and programming of JARA: a Modelica library of dynamic hybrid models of some fundamental physical-chemical principles; (3) the description of the JARA physical models in a way suitable for interactive simulation; and finally (4) the implementation of the virtual labs. This is illustrated by means of two case studies. Copyright © 2005 IFAC.
