Abstract
Provided is a method of controlling a permanent magnet generator, the method including: measuring mechanical noise of the generator; deriving two quantities indicative of an amplitude and a phase of an undesired harmonic of the measured noise; deriving, based on the quantities, a current to be injected in stator coils of the generator such as to reduce the undesired harmonic.
