Rotating stall is a fundamental aerodynamic instability phenomenon of axial flow compressors.Firstly

the results of nonlinear dynamic bifurcation analysis on Moore-Greitzer compression system model showed that rotating stall was induced by subsonic pitchfork bifurcation;secondly

an active nonlinear feedback control law was proposed which using compressor pressure ratio as input measuring signal and throttle valve position as output actuating signal;Finally

computer simulation in bifurcation software AUTO was carried

and the simulation results showed that the proposed active nonlinear feedback control law translated the pitchfork bifurcation from subsonic to supersonic

which could eliminate the hysteresis loop associated with rotating stall and extend the stable operating range of axial flow compressors.Moreover

the proposed control system only used 1-dimensional sensor and actuator

so it could be easily applied in the engineering field.
