ROTARY ELECTRIC MACHINE CONTROL APPARATUS AND CONTROL METHOD FOR ROTARY ELECTRIC MACHINE

摘要

A rotary electric machine control apparatus includes: a phase estimator configured to estimate a first estimated phase value based on a rotary electric machine current; a correction value storage configured to store correction information representing a plurality of second estimated phase values and a plurality of correction values; a first phase corrector configured to acquire, based on a second estimated phase value corresponding to the first estimated phase value, from the correction information, a correction value associated with the second estimated phase value, and configured to correct the second estimated phase values based on the correction value; a position controller configured to calculate a speed command based on a position command and the corrected second estimated phase value; and a speed controller configured to calculate a torque command value and a q-axis current command value based on the speed command and the corrected second estimated phase value.

1. A rotary electric machine control apparatus comprising:
a phase estimator 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 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 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 configured to calculate a speed command based on a position command and the corrected second estimated phase value; and a speed controller 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.
