Abstract :
We develop a globally stabilizing controller for a three-state lumped parameter centrifugal compressor surge model. The proposed model involves pressure and mass flow compression system dynamics as well as spool dynamics to account for the influence of speed transients on the compression surge dynamics. The proposed nonlinear controller architecture involves throttle and compressor torque regulation
