Comparison of Modelica and Matlab by Means of a Diesel Engine Model
Published April 19, 2004 by University of Salerno in Italy
Modelling and Simulation mostly takes place in signal-orientated programs like Matlab/Simulink. For some years the object-orientated modelling language Modelica and the simulation program Dymola have become well known. They provide a different approach to modelling where the simulation program as far as possible builds up the signal structure and manipulates the needed equations and claim to make modelling much easier and more systematic. This paper deals with a comparison of this approach using Modelica/Dymola with the known proceeding in Matlab/Simulink and the specific issues of these programs' usabilities. Whether the described claim can be fulfilled has been examined by rebuilding an existing model of a diesel engine in Modelica/Dymola and comparing model build-up, simulation, handling and analysis of both programs.
