In this paper we analyze the effects of fluid noise, actuator bandwidth, magnitude saturation and rate limits on rotating stall control by studying a two dimensional system which is the approximation of the dynamics on the attracting saddle-sink connections of the three state low $B$ parameter Moore Greitzer model together with the dynamics of the bleed valve controller. We show that the region of attraction to the stabilized rotating stall equilibria is seriously restrained by the fluid noise level, the actuator bandwidth, magnitude saturation and rate limits. The bandwidth and rate requirement for a fixed extension of stable region is estimated by calculating the stable manifold of the saddle fixed point of the two dimensional system.
