When an AC rotary machine having a rotor structure for generating saliency, and including first three-phase windings and second three-phase windings is controlled, a first position estimation command to be superimposed on a voltage command or a current command directed to each of the first three-phase windings and a second position estimation command to be superimposed on a voltage command or a current command directed to each of the second three-phase windings are set to have the same frequency, and caused to have a phase difference, thereby increasing an estimation accuracy of a rotation position of the AC rotary machine.
