ABSTRACT:
A method and system for reducing pulsations in the rotational speed of an engine in accordance with one embodiment of the present invention are disclosed. Torque applied by a supplemental torque source includes a component derived by pure feedback engine speed control and a learning feedforward component. The feedforward component predicts the oscillatory components in the torque generated by the engine.
