Abstract: A narrow band controller for suppressing disturbances from a source responsive to an input signal representative of the frequency spectrum of a disturbance from the source and providing an output signal having a similar frequency spectrum as the frequency spectrum of the input signal based on the input signal including delay logic for delaying, for a period of time, the received input signal for assuring the output signal has a phase different than the phase of said input signal.

Abstract: A system and method for damping narrow band axial vibrations of a rotating device in which a reaction mass is coupled to the rotating device and a reaction mass actuator is employed to move the reaction mass axially along the rotating device. An effect of vibrations on the rotating device is then measured, and in response the reaction mass is moved axially to damp the effect of vibrations and so the vibrations.
