Modeling and Simulation in Process Technology with Modelica
Günther Zauner, Felix Breitenecker · 2005
Many modeling and simulation tools have a lack of object orientation. So it is not possible to build true reusable components. Modelica is on the other hand a nice example of OO modeling language which can become a kind of international standard. In Modelica, a library which enables an efficient modeling in process technology, was implemented. All basic components of hydraulic systems such as the tank, pump, valve, … were included. The library was tested on a control systems design problem. Namely a PI controller and a cascade controller were designed with an optimization in Matlab. The example showed that the combination of Dymola- Modelica (for modeling) and Matlab-Simulink environments (for simulation and optimization) can be a very efficient tool for control system design.
