1. A control apparatus for an AC rotary machine that includes a first winding and a second winding and performs control operations on two rotary axes, comprising:

  • a current detection unit that detects a current of the first winding and a current of the second winding, respectively;

    a basic voltage calculation unit that calculates a basic voltage on the basis of a current command value and an electric constant of the AC rotary machine;

    a first voltage calculation unit that calculates a voltage command value of the first winding on the basis of the current command value, the basic voltage, and the current of the first winding;

    a second voltage calculation unit that calculates a voltage command value of the second winding on the basis of the current command value, the basic voltage, and the current of the second winding;

    a first voltage application unit that applies a voltage to the first winding of the AC rotary machine on the basis of the voltage command value of the first winding; and

    a second voltage application unit that applies a voltage to the second winding of the AC rotary machine on the basis of the voltage command value of the second winding,wherein the first voltage calculation unit calculates the voltage command value of the first winding on the basis of the current command value, the basic voltage, the current of the first winding, and also the current of the second winding.
