電動機の制御装置および制御方法、並びに物体検出装置
Document Type and Number:
Japanese Patent JP7226079
Kind Code:
B2
Abstract:
To control an electric motor by a desired rotational speed profile at the time of changing a rotational speed.SOLUTION: A control device 100 of an electric motor 20 has: a rotational speed detection unit 12 detecting a rotational speed of the electric motor 20 and outputting a detection rotational speed signal; and a control unit 10 setting an electric motor control signal for the electric motor 20 according to a demand rotational speed signal which can be changed at a rotation period of the electric motor 20 and the detection rotational speed signal and controlling the electric motor 20. The control unit 10 corrects the demand rotational speed signal so that a difference between the detection rotational speed signal and the demand rotational speed signal may be reduced or eliminated at the time of changing a demand rotational speed, and sets an electric motor control signal according to a processed demand rotational speed signal obtained by correction and a rotational speed detection signal.SELECTED DRAWING: Figure 1
