Abstract
A control apparatus, for a system including a rotating machine having a stator, around which a winding wire is wound, and a power conversion circuit, includes: a superimposition device that superimposes multiple harmonic currents, for converting a first electromagnetic force to a second electromagnetic force, on a fundamental wave current, the first electromagnetic force being a second or higher order electromagnetic force as a reduction object, the second electromagnetic force being a second or higher order electromagnetic force and different from the first electromagnetic force, an order of each harmonic current being between the first electromagnetic force and the second electromagnetic force; and a manipulation device that operates the power conversion circuit to flow the fundamental wave current, on which the harmonic currents are superimposed, in the winding wire.
