Synchronous Machine Control Device, Synchronous Machine Control Method, And Electric Vehicle

Abstract: According to the present invention, a synchronous machine control device that performs drive control of a synchronous machine comprises a current command computation unit that computes the difference between a current command value for the synchronous machine and the actual current flowing in the synchronous machine to generate a current command value by proportional integral control, a voltage vector computation unit that, on the basis of the current command value generated by the current command computation unit, generates a voltage command value that comprises an identical axis voltage command value and an orthogonal axis voltage command value, a voltage limitation unit that preferentially limits the identical axis voltage command value over the orthogonal axis voltage command value such that the voltage command value does not exceed a prescribed voltage limitation value, and a correction amount calculation unit that, on the basis of the voltage limitation by the voltage limitation unit, calculates a current command value correction amount for correcting the current command value. The current command computation unit corrects the current command value from the proportional integral control on the basis of the current command value correction amount.
