Abstract
The present invention relates to apparatus for stabilizing the operation of rotational machinery, particularly machinery which uses magnetic bearings. Accelerometers sense various vibrations within the machinery. The outputs of the accelerometers are analyzed by a Fast Fourier Transform algorithm and multiplied by an array of influence coefficients to calculate desired stabilizing forces to be applied to the rotating machinery. Compensating analog voltage signals are generated in accordance therewith and transmitted to magnetic control coils within the rotating machinery.
