| Zusammenfassung: | An object of the present invention is to provide a motor control apparatus having excellent harmonic current control performance, that can simplify circuit configuration and circuit processing while, at the same time, achieving improved control accuracy. To achieve this object, detected motor currents are converted by coordinate converters and into an nth-order dq-axis signal and an mth-order dq-axis signal, and their DC components are extracted by low-pass filters and ; then, the differences of the DC components relative to respective command values are converted back into three-phase AC signals to control the motor currents. |
