Abstract

Methods and systems are provided for improving surge control. When surge conditions are approached, a reference governor reduces engine airflow at a slower rate and to a higher level than the engine airflow required to meet the reduced torque demand. The excess torque resulting from the extra airflow is offset by applying a negative torque on the driveshaft via an electric machine coupled to the engine or via alternate engine actuator adjustments.
