Effects of Noise and Actuator Limits on Active Control of Rotating Stall and Surge |
Abstract |
Operability enhancement is one of the majo … Operability enhancement is one of the major goals for active control of rotating stall
and surge in aeroengines. The model developed by Moore and Greitzer exhibits the
qualitative behavior of rotating stall and surge dynamics and thus can be used for
controller designs. Based on this model, we derive a normal form from which explicit
relations between the stall and surge inception process and the shape of compressor
characteristics are obtained via bifurcation analysis. Analysis for the normal form with
bleed valve actuator dynamics shows that under certain circumstances the optimal control
is the "bang-on" control law that drives the bleed valve to open against its
rate limit once the disturbances grow out of the noise level. disturbances grow out of the noise level. +
