dc.description.abstractA pneumatic, pure fluid oontrol system, capable of maintaining the angular position of an inertia load in a gravitational space, using only one moving part, was designed and built. The control system consisted of a vortex-sink angular rate sensor, a pendulum controlled flapper-nozzle angular position sensor, a summing amplifier and bistable reaction jets. The system was designed to operate in a bang- bang manner in order to reduce errors in a minimum amount of time. A previous author's work on the vortex-sink angular rate sensor is extended to include information and data on proportional amplification of the output signal and the frequency response of the sensor. Methods for synthesizing the components into a working system are presented along with a theoretical analysis of the system's performance. Results of experiments performed on the completed system showed that the reaotion jets could be switched in a nearly optimal manner when responding to errors introduced on one side of the system, but, due to the unsymmetrical gain of the rate sensor, the errors introduced on the opposite side resulted in a certain amount of after end-point chattering. Good correlation between theory and experiment led to the conclusion that the application of standard control system design techniques can be readily applied to the design of pure fluid control systems.en_US
