Abstract:

This AASERT program augmented the original PRET program and supported work in three primary areas 1 dynamics and control of rotating stall, 2 nonlinear control of rotating stall using novel actuation, and 3 modeling of thin film deposition for superconducting thin films. The goal of the first two activities was to develop new insights and actuation technologies for rotating stall and surge, to overcome some of the limitations of traditional actuation techniques bleed valves and air injection. The goal of the third activity, begun after the initial student supported by the grant left Caltech, was to develop modeling and control approaches for complex, physical systems, including control of microstructural properties of materials using macroscopic actuation.
