Abstract
A multigroup, multiphase rotary electric machine control device including: a control target calculator to calculate an initial current command value of each phase based on a torque command value; a correction coefficient calculator to calculate a per-group correction coefficient corresponding to each group from a spatial mode M (M is 0 or a positive integer) of an electromagnetic force caused by magnetic flux density variation with respect to a rotational periodicity at the time of rotation of the multigroup, multiphase rotary electric machine; and a current command value corrector to calculate a current command value of the each phase, which is corrected based on the initial current command value and the per-group correction coefficient.
