Abstract
In a drive control apparatus for a multiple-winding motor including a power converter for driving a winding group per each winding group of a multiple-winding motor having a plurality sets of winding groups, a compensation amount calculator obtains, by using a signal of a first controller controlling a first power converter driving a first winding group among the winding groups, a compensation amount for compensating a signal of an other controller controlling an other power converter other than the first power converter, based on the compensation amount obtained by the compensation amount calculator. A signal of the other controller is compensated to control the other power converter, and the first power converter is controlled without compensating a signal of a first controller.
