A control apparatus is provided for controlling a multi-phase, switched reluctance motor. The control apparatus includes voltage adjusters, a controller, and a carrier signal generator. Each of the voltage adjusters adjusts a voltage applied to a corresponding one of voltage application targets on the same salient pole of a stator of the motor. The controller controls each of the voltage adjusters via a pulse-width modulation based on comparison between a command signal and a corresponding one of carrier signals, thereby controlling the voltage applied to the corresponding voltage application target to a command voltage indicated by the command signal. The carrier signal generator generates the carrier signals so that for at least one pair of the voltage application targets on the same salient pole of the stator, two of the carrier signals which respectively correspond to the pair of the voltage application targets are offset in phase from each other.
