Commuting operations on signal-flow graphs for visualization of interconnected systems
2011 (English)In: 4th IFAC Symposium on System, Structure and Control: Ancona Italy, 15-17 September 2010, New York: Curran Associates, Inc., 2011, 138-145 p.Conference paper (Refereed)
We explore the signal flow graph as a setup for visualizing and analyzing interconnected systems. Two operations for facilitating interpretation of signal flow graphs are defined. These are hiding of unimportant nodes and elimination of self-references and it is shown that the operations commute under some conditions and that the hiding operation preserves the physical structure of the system in a certain sense. Also, the Loop Gain Index (LGI) is introduced as a measure of the relative importance of the edges in terms of dynamic behavior of the interconnected system. The LGI isillustrated with a numerical example.
