Abstract
This paper deals with the reflectionless matching technique in fluidic networks.
On the basis of the theory of distributed parameter circuits, the perfect matching conditions in branched transmission line systems are introduced. Then, these conditions are reduced to the practical matching conditions in pneumatic systems.
The practical matching conditions in branched pneumatic transmission line systems can be summarized as follows.
(1) At the terminals, the transmission line must be loaded with its characteristic resistance.
(2) At the junctions, the total area of the cross sections of branching line must be equal to the cross sectional area of the main line.
Examples of matched transmission line systems and their theoretical and experimental responses to step inputs are presented to show the usefulness of this matching technique.
