A field-weakening controller determines a d-axis current command correction value in field-weakening control according to a modulation factor that correlates with the ratio of the voltage amplitude applied to the inverter to the power supply voltage. A d-axis current final value calculator outputs a d-axis current command final value calculated using a d-axis current command value and a d-axis current command correction value. A Current controller performs feedback control of the d-axis current command final value and the q-axis current command value. A d-axis current adjuster adjusts the d-axis current command final value based on the q-axis current command value so as to suppress an influence of the frequency component of the q-axis current command value in a specific frequency band for which at least a lower limit frequency is determined.
