Claim 14:
15. A method for controlling a motor, the motor rotating at a speed and the method comprising:
converting sense current signals from the motor to a rotational signal in a rotating reference frame;
receiving a first error input and provide a torque output, the first error input based on the torque component;
receiving a second error input and provide a flux output, the second error input based on the flux component;
receiving the torque component and a first reference input and provide a first error output based on the torque component;
receiving the flux component and a second reference input and provide a second error output based on the flux component;
receiving the first error output and provide a first output representing an attenuation of a harmonic of the torque component;
receiving the second error output and provide a second output representing the attenuation of a harmonic of the flux component;
receiving the torque output and the first output and provide an adjusted torque output; and
receive the flux output and the second output and provide an adjusted flux output; and
generating an output signal for control of the motor using the adjusted torque output and the adjusted flux output.
