Modeling Switching Networks Using Bond Graph Technique
Abstract
In this thesis, a novel approach to modeling a switching electrical/mechanical
network is introduced. The bond graph technique, the modeling tool in this
thesis, is explained and some examples are presented. The switching element
and its causality are discussed. The gearbox system is taken as a mechanical
switching network and after a brief description is modeled into a logical
switching network by means of the Karnaugh diagram, and thereafter translated
into bond graph representation. Further on, the derived algorithm is applied
to model a pilot ejection scenario. Additional issues regarding existing
analogies between electrical and mechanical systems are discussed. After a
short introduction to the modeling software Dymola, the generated models
are simulated and the validity of the results is analyzed.
