The invention is directed to a system and method for noise cancellation
for an apparatus such as an electric motors or generator. The system may
comprise a plurality of actuators, a plurality of phase controllers, each
phase controller receiving an input signal representing a movement of an
apparatus and outputting an output signal based on the input signal and
at least one predetermined phase shift, and a plurality of amplifiers,
each amplifier receiving an output signal from one of the phase
controllers and outputting an amplified signal to drive one of the
actuators. The method may comprise the steps of generating a first signal
representing a movement of the apparatus, generating at least one second
signal based on (a) the first signal, (b) at least one predetermined
phase shift, and (c) at least one predetermined amplitude, and driving at
least one actuator with the at least one second signal.
