摘要 |
A motor drive control device includes: a generation part for generating a current command value; a current detection part for detecting a drive current of an electric motor; a motor feedback control part for controlling feedback of the electric motor based on the current command value and a drive current detection value; a prefilter with order of one or more for adjusting the current command value, the prefilter being interposed between the generation part and the motor feedback control part; and a series compensator with order of two or more for determining a voltage command value of the motor feedback control part based on the current command value adjusted by the prefilter and the drive current detection value of the electric motor. |
