Claim 7:
8. A motor controller integrated circuit (IC), comprsing:
a three-phase inverter for a motor; and
circuitry coupled to three-phase inverter, the circuit configured to:
convert motor sense currents to a signal in a rotating reference frame having a torque component and a flux component;
receive a first error input and provide a torque output the first error input based on the torque component;
receive a second error input and provide flux output, the second error input based on the flux component;
receive the torque component and a first reference input and provide a first error output based on the torque component;
receive the flux component and a second reference input and provide a second error output based on the flux component;
receive the first error output and provide a first output representing an attenuation of a harmonic of the torque component;
receive the second error output and provide a second output representing the attenuation of a harmonic of the flux component;
receive 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
generate an output signal for control of the motor using the adjusted torque output and the adjusted flux output.
