Abstract
To provide an AC rotary machine controller which can improve setting accuracy of torque command correction value in a region where change of torque command correction value to change of rotational speed and torque becomes large and where nonlinearity is high, and can suppress increase in data amount of correction value setting map. In correction value setting map, one or both of a torque axis unequal interval setting that sets interval of the torque command map axis to unequal interval in each rotational speed; and a rotation axis unequal interval setting that sets interval of the rotational speed map axis to unequal interval were done.
