Claim 0:
1. A method of generating a converter control signal for a generator side converter portion being coupled to a generator, the method comprising:
deriving at least one harmonic torque reference based on a harmonic torque demand and a torque indicating feedback signal;
deriving at least one harmonic flux reference based on a harmonic stator voltage demand and a stator voltage indicating feedback signal;
adding all of the at least one harmonic torque reference to a fundamental torque reference and subtracting an estimated generator torque to derive a torque error;
adding all of the at least one harmonic flux reference to a fundamental flux reference and subtracting an estimated generator flux to derive a flux error; and
deriving the converter control signal based on the torque error and the flux error.
