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.
