Bond Graphs
The topic area that has become commonly known as ‘bond graph modeling and simulation’ should be separated into at the one hand the port-based approach to modeling and simulation and at the other hand the bond graph notation that is well suited to represent the port-concept. For this reason both the notation and the concepts directly related to the notation will be separated as much as possible ...
متن کاملThe Mathematical Foundations of Bond Graphs-I. Algebraic Theory
Elementary mathematical concepts from linear algebra are used to develop an independent theory for non-directed bond graphs. The dejinition of a bond graph is given and its structure as a combinatorial object is studied. This is accomplished by constructing a vector space, called the bond space of the bond graph. Topological information is encoded in the bond graph by dejining a subspace of the...
متن کاملBond Graphs III: Bond Graphs and Electrical Networks
Electrical networks are defined and a definition of when a bond graph and an electrical network are equivalent is given. Bond graphs and electrical networks are defined to be primitive if they contain no transformers or gyrators. A bond graph is defined to be realisable if it is equivalent to an electrical network and primitively realisable if it is equivalent to a primitive electrical network....
متن کاملDomination Equivalence in Graphs
A de-pair (ode-pair) in a graph consists of two disjoint subsets of vertices with the same closed neighborhood (open neighborhood). We consider the question of determining the smallest and largest subsets over all such pairs. We provide sharp bounds on these for general graphs and for trees, and show that the associated parameters are computable for trees but intractable in general.
متن کاملBicausal Bond Graphs
P.J. Gawthrop Centre for Systems and Control, University of Glasgow. [email protected] Key Words| Bond graphs; causality; system inversion; parameter estimation Abstract|Conventional bond graph theory is predicated on the notion that a bond has a single causal stroke: an effort imposed at one end implies a ow imposedat the other. This notion is implied by components having a known consti...
