A control apparatus is provided to control a rotating electric machine whose number of poles is switched from a pre-switching number of poles to a post-switching number of poles. The control apparatus includes a pre-switching control unit, a post-switching control unit and a transition control unit. The pre-switching control unit controls the torque generated by the machine before the switching of the number of poles. The post-switching control unit controls the torque generated by the machine after the switching. During a pole-number switching period, the transition control unit controls electric currents flowing in stator coils of the machine or voltages applied to the stator coils to make each magnetic pole formed with control by the pre-switching control unit not coincident with any magnetic pole formed with control by the post-switching control unit and having the same polarity as the magnetic pole formed with the control by the pre-switching control unit.
