Abstract
In a control apparatus, a target harmonic current obtainer obtains, according to a phase current flowing through at least one phase winding of a stator, a target harmonic current component flowing in a rotary machine. The target harmonic current component is included in a fundamental current component of the phase current. An inducing unit superimposes, on the phase information, a fluctuating signal that changes at an angular velocity identical to an angular velocity of the target harmonic current component, to induce a counteracting harmonic current component in the at least one phase winding. The counteracting harmonic current component counteracts the target harmonic current component.
