Computer Aided Design For Fluidic Sequential Circuits Of Fundamental Mode, Yau-Hwang Lee Jul 1975

Computer Aided Design For Fluidic Sequential Circuits Of Fundamental Mode, Yau-Hwang Lee

Dissertations and Theses

This thesis presents the method of state diagram synthesis and the development of a computer program for designing fluidic sequential feedback control circuits of the fundamental mode. A paper on state diagram synthesis was authored by Chen and Lee, presented in Detroit and published as ASME paper 73-WA/Flcs-2 in 1973.

Hypothetical systems are illustrated by using series of events characterized by the piston positions of some double-acting pneumatic cylinders. In these systems , an action can only begin when the previous action has been completed. Every extension or retraction of a piston is memorized and manifested by a flip-flop element …
