Disclosed is a synchronous machine control device capable of suitably executing stabilization control of a synchronous machine. This synchronous machine control device controls a power converter (2) to which a synchronous machine (1) is connected, and comprises: a first magnetic flux command calculation unit (21) that calculates a first magnetic flux command value from an electric current command value of the synchronous machine; a magnetic flux estimation unit (23) that estimates a magnetic flux value of the synchronous machine from an electric current detection value of the synchronous machine; a voltage calculation unit (19) that generates a voltage command value for the power converter such that the first magnetic flux command value and the magnetic flux value match; and a damping ratio control unit (27) that, on the basis of a vibration component of the magnetic flux value, generates a correction amount for the voltage command value such that the vibration component is damped.
A synchronous machine control device that controls a power converter to which a synchronous machine is connected, the synchronous machine control device comprising:
A synchronous machine control method for controlling a power converter to which a synchronous machine is connected, the method comprising:
An electric vehicle driven by a synchronous machine, comprising:
