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.
Claims18
A method comprising:
- determining a rotational position of a rotating shaft;
- determining at least one characteristic indicative of an amount of torsional vibration in the rotating shaft;
- and
- controlling an actuator that is coupled to the rotating shaft based on the rotational position of the rotating shaft and the at least one characteristic.
