Abstract
A control apparatus for AC rotating machine includes: a voltage command calculation means for calculating voltage commands on two rotational axes; a first voltage application means for applying voltages to first windings of a multiple-winding AC rotating machine having at least the first windings and second windings based on the voltage commands on two rotational axes output by the voltage command calculation means; and a second voltage application means for applying voltages to the second windings based on the voltage commands on two rotational axes output by the voltage command calculation means, wherein the second voltage application means applies voltages to the second windings based on the deviations between the currents fed to the first windings and the currents fed to the second windings.
