Abstract
A rotary electric machine control device includes a positive/negative determination section that determines whether an output torque of the rotary electric machine is positive or negative; a correction parameter setting section that sets as a correction parameter a phase difference of a sinusoidal ripple correction wave for reducing torque ripple of the rotary electric machine with respect to a magnetic pole position of the rotary electric machine depending on whether the output torque is positive or negative; and a correction wave generation section that generates the ripple correction wave on the basis of the correction parameter.

A rotary electric machine control device that controls driving of a rotary electric machine that drives a vehicle, comprising:
- a positive/negative determination section that determines whether an output torque of the rotary electric machine is positive or negative;
- a correction parameter setting section that sets as a correction parameter a phase difference of a sinusoidal ripple correction wave for reducing torque ripple of the rotary electric machine with respect to a magnetic pole position of the rotary electric machine depending on whether the output torque is positive or negative;
- and
- a correction wave generation section that generates the ripple correction wave on the basis of the correction parameter,
- wherein the rotary electric machine is controlled to drive using the ripple correction wave.
