Abstract
A control apparatus for an AC rotary machine includes a current detection unit that detects a current of a first winding and a current of a second winding, a basic voltage calculation unit that calculates a basic voltage on the basis of a current command value, 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, and 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. At least the first voltage calculation unit calculates the voltage command value of the first winding by further taking into account the current of the second winding.
