POG Modeler: the Web Power-Oriented Graphs Modeling Program

Abstract In this paper the Power-Oriented Graphs (POG) technique is introduced and a new modeling program named “POG Modeler”, freely available on the web, is presented. In the POG Modeler program the physical systems can be defined graphically using an ascii commend-line interface and referring to predefined graphic symbols. The POG Modeler automatically analyzes the given physical system and provides the following outputs: 1) the differential equations of the given system in symbolic form: 2) The POG block scheme of the considered system; 3) the Simulink block scheme of the given system ready for the Matlab environment. The POG systems are simple block schemes that can be easily used also by beginners.
