A synchronous machine control apparatus for correcting a rotor position error that is a difference between a rotor position of a synchronous machine and a rotor position detected by a position detection unit is provided with a current control device for performing control in such a way that respective current command values and respective current detection values in a generation direction (γ axis) of an armature interlinked magnetic flux and in a direction perpendicular (δ axis) to the generation direction of the armature interlinked magnetic flux coincide with each other and with a magnetic flux calculation device for calculating a phase of an armature interlinked magnetic flux, based on an armature current detection value of the synchronous machine and an armature voltage command value therefor; the rotor position error is corrected based on the γδ-axis current command values and a phase of the armature interlinked magnetic flux. |
