Abstract
(EN)
In steps S54 to S55, if the rate of change Δτ* in the torque command value to a motor 10 is equal to or greater than a predetermined value, the frequency switching speed Δfc of carrier frequency fc is set on the basis of the rotational speed N of the motor 10 so that the response frequency ωfc of the frequency switching speed Δfc of the carrier frequency fc is faster than the response frequency ωACR of a current control unit 70. In steps S54 and S56, if the rate of change Δτ* in the torque command value to the motor 10 is less than the predetermined value, the frequency switching speed Δfc of the carrier frequency fc is set on the basis of the torque command value τ* to the motor 10 and the rotational speed N of the motor 10 independently of the response frequency ωACR of the current control unit 70. According to the present invention, it is possible to, while preventing the response of the motor control device from deteriorating, suppress the torque fluctuation at the time of switching of the carrier frequency and stably drive the motor over a wide operation range .

Selon l'invention, dans les étapes S54 à S55, dans lesquelles, si la vitesse de changement Δτ* dans la valeur d'instruction de couple à un moteur (10) est égale ou supérieure à une valeur prédéterminée, la vitesse de commutation de fréquence Δfc de la fréquence porteuse fc est réglée sur la base de la vitesse de rotation N du moteur (10) de telle sorte que la fréquence de réponse ωfc de la vitesse de commutation de fréquence Δfc de la fréquence porteuse fc soit plus rapide que la fréquence de réponse ωACR d'une unité d'instruction de courant (70). Dans les étapes S54 et S56, si la vitesse de changement Δτ* dans la valeur d'instruction de couple au moteur (10) est inférieure à la valeur prédéterminée, la vitesse de commutation de fréquence Δfc de la fréquence porteuse fc est réglée sur la base de la valeur d'instruction de couple τ* au moteur (10) et de la vitesse de rotation N du moteur (10) indépendamment de la fréquence de réponse ωACR de l'unité d'instruction de courant (70). Selon la présente invention, il est possible, tout en empêchant la détérioration de la réponse du dispositif de commande de moteur, de supprimer la fluctuation de couple au moment de la commutation de la fréquence porteuse et d'entraîner de manière stable le moteur sur une large plage de fonctionnement.

ステップS54~ステップS55で、モータ10へのトルク指令値の変化率Δτ*が所定値以上の場合は、モータ10の回転数Nに基づいて、キャリア周波数fcの周波数切替速度Δfcの応答周波数ωfcが電流制御部70の応答周波数ωACRよりも早くなるように、キャリア周波数fcの周波数切替速度Δfcを設定する。ステップS54、ステップS56で、モータ10へのトルク指令値の変化率Δτ*が所定値未満の場合、モータ10へのトルク指令値τ*とモータ10の回転数Nとに基づいて、電流制御部70の応答周波数ωACRに関わらず、キャリア周波数fcの周波数切替速度Δfcを設定する。本発明によれば、モータ制御装置の応答劣化を防いだうえでキャリア周波数の切替時のトルク変動を抑制でき、モータを広い運転範囲で安定して駆動することができる。
