Synthesis methodology for active element using impedances–based bond graph methods

Abstract

This paper introduces a synthesis methodology for active elements within systems that uses frequency response function as a basis for describing required behavior. The method is applicable in the design of a new system or in the retrofit of an existing system in which an active element is required or desired. The two basis principles of bond graph modeling are the “reticulation principle” which decomposes a physical into elemental physical laws represented as network elements interacting through ports and the “power postulate” which assembles the complete model through a network of power flows representing the exchange of energy between the elements. Moreover the bond graph model leads to a rigorous definitions of the structure of the associated dynamical equations.
