Abstract

A controller of an AC motor includes a d-axis voltage command section to generate a d-axis voltage command on a d axis of a d-q coordinate system. A d-axis non-interactive control section removes, from the d-axis voltage command, an interference component resulting from a current on a q axis of the system. A first current deviation arithmetic section obtains a deviation between a current command on the q axis and the current on the q axis flowing through the AC motor. A q-axis integral control section outputs an integral value of the deviation. A q-axis voltage command section generates a q-axis voltage command based on the deviation. A constant output control section outputs a correction voltage command based on the integral value. A d-axis voltage command correction section subtracts the correction voltage command from the d-axis voltage command after non-interactive control to correct the d-axis voltage command.
