Title:
ELECTRIC MACHINE CONTROLLING METHOD AND ELECTRIC MACHINE CONTROLLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/106727
Kind Code:
A1
Abstract:
A control device 100, which performs either a voltage phase control or an electric current vector control so as to control electric power supply to an electric machine 9 according to the operating state of the electric machine 9, calculates a voltage command value for the voltage phase control on the basis of a voltage norm command value indicating the magnitude of a supply voltage for the electric machine 9 and of a voltage phase command value indicating the phase of the supply voltage. The control device 100 calculates, on the basis of an electric current supplied to the electric machine 9, a state amount of either a magnetic flux generated in the electric machine 9 or a parameter correlated with the magnetic flux, and changes the voltage norm command value according to the state amount.
