Zusammenfassung: | Provided is an electric motor control method includes: calculating a second torque command value by correcting the first torque command value by a vibration compensation torque for suppressing vibration in an electric motor rotation speed; limiting the vibration compensation torque based on a limit request suggesting amount suggesting a situation in which suppression of vibration in the electric motor rotation speed is to be limited; determining a limit level representing a degree of limit on the vibration compensation torque; and calculating a voltage command value by feeding back a torque suggesting amount suggesting an electric motor torque to the second torque command value. In the torque control step, a feedback gain of the torque suggesting amount is determined with reference to the limit level. |
