Title:
DRIVE CONTROL DEVICE, DRIVE DEVICE, AND POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/031526
Kind Code:
A1
Abstract:
One embodiment of a drive control device is a drive control device for controlling driving of a three-phase motor, the drive control device comprising: an imbalance calculation unit that calculates an electrical imbalance between the phases of the three-phase motor; a control value calculation unit that calculates, in accordance with a supplied target, a control value for a current in each axial direction of a rotational coordinate system of the 3-phase motor; and a balance compensation unit that reduces the imbalance by adding compensation values to the control values for the currents in axial directions other than a q axis direction, such control values from the control values calculated by the control value calculation unit.
