Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 assoc…
