| abstract =  In this paper we evaluate the actuator rate requirements for control of rotating stall
using a bleed valve and provide tools for predicting these requirements. Modification of
both the stable and unstable parts of the compressor characteristic via addition of
continuous air injection serves to reduce the requirement of a bleed valve used for the
purpose of rotating stall stabilization. Analytical tools based on low order models (2-3
states) and simulation tools based on a reduced order model (37 states) are described. A
bleed actuator rate limit study is presented to compare the actuator requirements
predicted by theory, simulation, and experiment. The comparisons show that the predictions
obtained from theory and simulations share the same trend as the experiments, with
increasing accuracy as the complexity of the underlying model increases. Some insights on
the design of a bleed-compressor pair are given.
