Title:
PERMANENT MAGNET SYNCHRONOUS MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/194396
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a permanent magnet synchronous machine control device capable of calculating a correction value of a magnetic pole position with a simple configuration. A first correction phase calculation unit (9) of the control device (1) calculates a first correction phase on the basis of a d-axis voltage command value calculated by a current control unit (8). A second correction phase calculation unit (10) of the control device (1) calculates a second correction phase on the basis of at least either a q-axis current command value calculated by the current control unit (8) or the actual value of the q-axis current of a permanent magnet synchronous machine and a parameter of the permanent magnet synchronous machine. A conversion unit of the control device (1) performs a coordinate transformation on the d-q coordinate of the current control unit (8) using the electrical angle of the permanent magnet synchronous machine corrected by a third correction phase. The third correction phase is the sum of the first correction phase and the second correction phase.
