Combined Air Injection Control of Rotating Stall and Bleed Valve Control of Surge

Robert L. Behnken and Richard M. Murray
1997 American Control Conference

Previous work at Caltech has developed a controller for rotating stall in axial flow compressors using pulsed air injection. In this work, theory is developed for the combination of this air injection controller with a bleed valve controller for the system's surge dynamics. The controller analysis is based on the surge dynamics acting on a slow time scale relative to the rotating stall dynamics. Experiments demonstrating this controller design on the Caltech rig are also presented.
