A three-phase permanent magnet motor is controlled by generating two-phase control signals. A rotation speed value is generated representing a rotation speed of the permanent magnet motor 101 based on a q-current reference value and a q-current feedback value, the q-current reference value and the q-current feedback value corresponding to a q-phase winding. A d-phase voltage change value is generated based on a d-current reference value and a d-current feedback value, the d-current reference value and the d-current feedback value corresponding to the d-phase winding. A first d-phase voltage value is generated based on the rotation speed value, the d-phase voltage change value, the d-current reference value and the q-current reference value. A first q-phase voltage value is generated based on the rotation speed value, the q-current reference value and the d-current reference value. |
