Abstract
A method for damping torsional vibrations in a rotating shaft. The method includes coupling an actuator to a shaft; rotating the shaft; determining an amount of torsional vibration in the shaft; and controlling the actuator in response to the amount of torsional vibration and a rotational position of the shaft to damp the torsional vibration in the shaft.
