Title:
CONTROL DEVICE OF ROTATING ELECTRIC MACHINE AND ELECTROMOTIVE POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/113317
Kind Code:
A1
Abstract:
Provided are a control device of a rotating electric machine and an electromotive power steering device, the control device being able to set a control gain for controlling a d-axis current command value in consideration of the responsiveness of a q-axis current on the basis of a q-axis current difference between a q-axis current command value and a q-axis current detection value. The control device (10) of the rotating electric machine changes the d-axis current command value (Ido) and changes a proportional gain (Kpid) in reverse proportion to a rotational angular velocity (ω) on the basis of a value obtained by multiplying the proportional gain (Kpid) by the q-axis current difference (ΔIq_err) that is the difference between the q-axis current command value (Iqo) and the q-axis current detection value (Iqs).
