Abstract:

This thesis presents the design of a pressure control system for the Compressor Research Facility CRF. Using a fluid dynamics model of the CRF, a controller was designed to track commanded test chamber pressure while the test compressor operated at varying speeds. This was accomplished by adjusting CRF inlet valves first with a coarse open-loop gain schedule, then closing the loop with a digital dynamic compensator for fine adjustments. The design was simulated on a digital computer and coded for incorporation into the CRFs current control algorithm.
