Abstract :
The compressor stall/surge model of Moore and Greitzer (1986) is extended to include the spool dynamics. This results in a model with four states, where the new state is the B-parameter. The effect of a time varying B-parameter on the post stall transients of an axial compressor is demonstrated through simulations of a compression system with speed control
