A control device for an AC rotating machine includes: an inverter configured to apply a voltage to the AC rotating machine; a DC power supply configured to supply DC power to the inverter; an electric current detector configured to detect a rotating machine electric current flowing through the AC rotating machine; a first axis voltage command value calculator configured to calculate a voltage command value of a first axis between two rotational axes of the AC rotating machine; and a second axis voltage command value calculator configured to calculate a voltage command value of a second axis between the two rotational axes. The first axis voltage command value calculator calculates the voltage command value of the first axis based on a corrected first deviation obtained by multiplying a first deviation by a correction gain, a second deviation, and a rotational angular velocity. A set value of the correction gain is increased when a physical quantity in the AC rotating machine has rapidly changed or when an output voltage of the DC power supply has increased.
