PM CURRENT CONTROL GAIN ADJUSTING METHOD FOR PM MOTOR CURRENT CONTROL METHOD AND CONTROL DEVICE

摘要

According to the present invention, there is provided a method of controlling a motor, comprising: a voltage applying step of applying an applied voltage including a direct current component and a plurality of frequency components to a PM motor; a motor current detecting step of detecting a motor current flowing in accordance with the applied voltage; And a current control gain adjustment step of calculating a current control gain based on the characteristic of the current control gain. This makes it possible to adjust the current control gain that is stable and high in current responsiveness in a short time.
