Abstract
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, and it is felt that an order of magnitude improvement could result from an improved design.
