| description abstract | We have applied feedback control to the compressor of a 45 kW auxiliary power unit. Using this, the engine is able to deliver more than 10 percent extra shaft power before surge occurs. We achieve control by suppressing a nonaxisymmetric flow phenomenon in the diffuser of the centrifugal compressor. Control is effected by modulating a small extra airflow into the impeller. We present results of modeling and analysis suggesting that linear feedback control will be sufficient to stabilize a compression system, even when both axisymmetric surge and rotating stall are present as possible instabilities. | |
