Previous results in the use of pulsed air injection for
active control of rotating stall have suggested that air injectors
have the effect of shifting the steady state compressor
characteristic.  In this paper we analyze the effect of a compressor
characteristic actuation scheme for the three state Moore Greitzer
compression system model.  It is shown that closed loop feedback based
on the square magnitude of the first rotating stall mode can be used
to decrease the hysteresis region associated with the transition from
unstalled to stalled and back to unstalled operation.  The compressor
characteristic shifting idea is then applied to a higher fidelity
distributed model in which the characteristic shifting has phase
content in addition to the magnitude content captured by the three
state model.  The optimal phasing of the air injection relative to the
sensed position of the stall cell is determined via simulation and the
results found to agree with those obtained via an experimental
parametric study on the Caltech low-speed axial flow compressor.}
