Abstract
A rotary electric machine control device that controls a rotary electric machine that includes a rotor in which a permanent magnet is disposed so as to provide magnetic saliency, and that performs feedback control on the rotary electric machine on the basis of a deviation between a current command and a feedback current from the rotary electric machine in a d-q-axis vector coordinate system defined by a d-axis which extends in a direction of a magnetic field produced by the permanent magnet and a q-axis which is orthogonal to the d-axis.
