| abstract |
An object of the present invention is to achieve both suppression of an increase in processing load of a control unit and securing of controllability of a motor. A control unit that controls an inverter by PWM control sets a d-axis and q-axis voltage command based on a motor torque command and a detected electrical angle as a motor electrical angle detected by a detection unit. One calculation process is executed at one cycle interval of the carrier wave, and a second calculation process including a process of calculating a predicted electric angle used for generating the PWM signal based on the detected electric angle is executed at half cycle intervals of the carrier wave.
