Abstract
A current controller calculates a drive signal by means of fundamental wave current control and high-order current control, for driving an inverter. A 5order/7order voltage command calculation section calculates a 5order/7order voltage command vector Vd*, Vq* by means of feedback control which makes a high-order dq transformation value extracted from the actual current coincide with a 5order/7order current command value Id*, Iq*. A 5order/7order vector transformation section executes high-order vector transformation processing on the 5order/7order voltage command vector Vd*, Vq* that is calculated by the 5order/7order voltage command calculation section, with the high-order vector transformation processing being executed such as to make a high-order voltage vector and a high-order current vector coincide in phase in high-order dq coordinates, and with the high-order vector transformation processing including rotation transformation by high-order vector rotation which rotates a high-order vector.
