Title:
ROTARY MACHINE CONTROL DEVICE AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/219795
Kind Code:
A1
Abstract:
A rotary machine control device comprising: a first inverter that, on the basis of a first DC voltage, applies an AC voltage to a 3-phase winding in a first system in a rotary machine; a second inverter that applies an AC voltage to a 3-phase winding in a second system in the rotary machine; a first control unit that, on the basis of a command value for the rotary machine and a minimum DC voltage being the lower out of the first DC voltage and a second DC voltage, generates a command value for d-axis current for the first system, generates a command value for a q-axis current for the first system on the basis of the minimum DC voltage and the command value for the d-axis current for the first system, and controls the first inverter on the basis of the command value for the d-axis current for the first system and the command value for the q-axis current for the first system; and a second control unit that, on the basis of a minimum DC voltage and a command value for the rotary machine, generates a command value for d-axis current for the second system, generates a command value for a q-axis current for the second system on the basis of the minimum DC voltage and the command value for the d-axis current for the second system, and controls the second inverter on the basis of the command value for the d-axis current for the second system and the command value for the q-axis current for the second system.
