Abstract
(EN) The electric motor speed control device of an embodiment comprises a rotational speed estimation unit and a control unit. The rotational speed estimation unit uses the FFT analysis result of a speed detection signal ωFBK based on the detection result of a resolver for detecting the rotational speed of an electric motor and the speed detection signal ωFBK to generate an estimated value of the rotational speed of the electric motor. The control unit performs speed control so that the deviation between a speed command value for the speed control of the electric motor and the estimated value of the rotational speed becomes small.
(FR) Dispositif de commande de vitesse de moteur électrique d'un mode de réalisation comprenant une unité d'estimation de vitesse de rotation et une unité de commande. L'unité d'estimation de vitesse de rotation utilise le résultat d'analyse FFT d'un signal de détection de vitesse ωFBK basé sur le résultat de détection d'un résolveur pour détecter la vitesse de rotation d'un moteur électrique et le signal de détection de vitesse ωFBK pour générer une valeur estimée de la vitesse de rotation du moteur électrique. L'unité de commande effectue une commande de vitesse de telle sorte que l'écart entre une valeur d'instruction de vitesse pour la commande de vitesse du moteur électrique et la valeur estimée de la vitesse de rotation devient petit.
(JA) 実施形態の電動機速度制御装置は、回転速度推定部と、制御部とを備える。前記回転速度推定部は、電動機の回転速度を検出するレゾルバの検出結果に基づいた速度検出信号ωFBKのFFT解析の結果と、前記速度検出信号ωFBKとを用いて前記電動機の回転速度の推定値を生成する。前記制御部は、前記電動機の速度制御の速度指令値と前記回転速度の推定値との偏差が小さくなるように速度制御を実施する。
