AN ADAPTIVE CONTROLLER FOR MULTIVARIABLE ACTIVE NOISE CONTROL

Vibration through the mounts of rotating machines can be controlled by actively generating cancelling forces from shakers located close to the mounts. The cancelling vibrations cannot simply be an anti- phase copy of the original waveform, since each shaker affects the vibration at mounts other than the one it is cancelling. This paper describes an approach to this multivariable control problem which measures all shaker to sensor transfer functions to give a shaker transfer function matrix. The system is adaptive and can cope with slowly varying noise spectra; cancellations of better than 25 dB have been achieved.
