Title:
ROTATING MACHINE CONTROL DEVICE, MACHINE LEARNING DEVICE, AND INFERENCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/244204
Kind Code:
A1
Abstract:
This rotating machine control device (20) comprises: a current detector (12) that detects the AC current flowing through a rotating machine and outputs a current detection value; a power converter (11) that supplies power to the rotating machine by applying an AC voltage based on a voltage command value; a current controller that adjusts the voltage command value so that the current detection value is consistent with a current command value; an estimator (2) that obtains a magnetic flux estimation value that is the estimated value of the amplitude of a magnetic flux vector of the rotating machine; and a magnetic flux controller that adjusts the current command value so that the magnetic flux estimation value is consistent with a set magnetic flux command value during a start-up control period from when the power supply by the power converter (11) is shut off and the rotating machine is brought into a state of rotating through inertia until the power supply is resumed.
