Dissertations and Theses
This thesis reviews the design and analysis of a fluidic/pneumatic position servo. Rolling diaphragm piston actuators are used for the system drive, and a hydrostatic gas journal bearing is used as the position sensor. The servo has a 1 inch range which is monitored using an electrical capacitive position transducer that was built as an integral part of the system.
Open-loop frequency response testing provides the basis for a mathematical model of the system.
The servo response is linear at frequencies up to 3 Hertz.
The frequency response appeared to be limited by the design of the gas bearing sensor, …
