Abstract

A rotary electric machine control apparatus includes: a phase estimator (109) configured to estimate a first estimated phase value relating to an estimated phase of a rotor based on a rotary electric machine current flowing through a rotary electric machine; a correction value storage (113) configured to store correction information representing a plurality of second estimated phase values and a plurality of correction values relating to the estimated phase in association with each other; a first phase corrector (114, 115) configured to acquire, based on one of the plurality of second estimated phase values corresponding to the first estimated phase value, from the correction information, one of the plurality of correction values associated with the one of the plurality of second estimated phase values, and configured to correct the one of the plurality of second estimated phase values based on the one of the plurality of correction values; a position controller (101) configured to calculate a speed command based on a position command and the corrected second estimatedphase value; and a speed controller (102) configured to calculate one of a torque command value and a q-axis current command value based on the speed command and the corrected second estimated phase value.
