MULTIGROUP-MULTIPHASE ROTATING ELECTRICAL MACHINE CONTROL DEVICE AND MULTIGROUP-MULTIPHASE ROTATING ELECTRICAL MACHINE DRIVE DEVICE

摘要

A multigroup-multiphase rotating electrical machine control device 1 for controlling a multigroup-multiphase rotating electrical machine having an arrangement of different groups of windings at locations of mechanical spatial phases differing by 180/N (N being an integer 2 or higher) degrees, wherein the control device is provided with: a control target computation unit 410 for calculating initial current command values for respective phases on the basis of a torque command value; a correction factor calculation unit 411 for calculating respective group correction factors corresponding to respective groups from a spatial mode M (M being 0 or a positive integer) of electromagnetic force caused by a variance in magnetic flux density relative to a rotational periodicity during rotation of the multigroup-multiphase rotating electrical machine; and a current command value correction unit 412 for calculating current command values of respective phases that have been corrected on the basis of the initial current command values and the respective group correction factors.
