Dynamic Simulation of a Free-Piston Linear Alternator in Modelica

Kurzfassung

This paper presents the modeling and simulation of a novel development of a free-piston engine in Modelica. The investigated concept is a combination of a combustion process and a linear alternator designed to provide clean, efficient energy in a compact engine. To study the features of free-piston engines a Modelica library is outlined containing basic and advanced component models. Detailed sub-models are investigated in order to design and improve hardware components. Control strategies are developed and dynamically tested within the Modelica simulation. Dymola/Modelica was found to be the best tool to examine the dynamic system behavior.
