A motor control apparatus having a fundamental wave current control circuit that
implements feedback control on a fundamental wave component of a motor current
in a dq coordinate system rotating in synchronization with the rotation of the
motor and a higher harmonic current control circuit that implements feedback control
on a higher harmonic components of the motor current in a dhqh coordinate system
rotating with a frequency which is an integral multiple of the frequency of the
fundamental wave component of the motor current, eliminates the higher harmonic
component of the motor current from the control deviation between a fundamental
wave current command value and a motor current feedback value.
