Abstract:
A current instruction generation unit generates a d-axis current instruction and a q-axis current instruction based on a torque instruction for an AC motor, using a map in which a current instruction capable of lowering noise (vibration and sound noise) (low-noise current instruction) generated from the AC motor is determined in advance for each torque of the AC motor. Then, a signal for driving an inverter is generated based on the generated d-axis current instruction and the q-axis current instruction.
