Zusammenfassung: | A motor control apparatus for controlling a DC motor includes a detection means (203) configured to detect an angular speed of the DC motor, and a control means (203) configured to, when the DC motor is started, perform feedforward control of linearly increasing a control value input to the DC motor from a first control value corresponding to an angular speed lower than a target angular speed up to a second control value corresponding to an angular speed higher than the target angular speed, then switch over to feedback control of keeping the DC motor at the target angular speed based on a detection result of the detection means (203) in response to the detection result of the detection means (203) reaching the target angular speed. |
