Shape signifiers for throttle control of a low-order compressor model
- AUTHOR: Rodolphe Sepulchre and Petar Kokotovic
- ABSTRACT: Rotating stall and surge, two instability mechanisms limiting the performance of aeroengines compressors, are studied on the third-order Moore-Greitzer model. The {\it skewness} of the compressor characteristic, a single parameter shape signifier, is shown to determine the key qualitative properties of throttle feedback control.
