ELECTRIC MOTOR CONTROL DEVICE

WIPO Patent Application WO/2013/128799

A1

Provided is an electric motor control device whereby vibration can be reduced in a zone of high-frequency speed fluctuation. The electric motor control device comprises: a target rotational speed setting section that sets a target rotational speed of the electric motor; a rotational speed inferring section that calculates an inferred rotational speed of the electric motor; and a drive instruction signal generating section that generates a drive instruction signal of the electric motor such as to eliminate the difference of rotational speed between the target rotational speed and the inferred rotational speed. The rotational speed inferring section is provided with: an error calculation section that calculates an error in relation to the rotation of the electric motor; and an inferred corrected rotational speed calculation section that calculates an inferred corrected rotational speed by inputting the error and correcting the inferred rotational speed.
