Abstract

See full text

A control device for a power conversion device according to an embodiment includes a drive control unit controlling a current that is caused to flow through a stator winding of a motor, a drive quantity adjustment unit calculating a drive quantity command value defining a drive quantity of the motor, a magnetic flux observer calculating calculates a first estimated value of a stator magnetic flux of the motor and a first estimated value of a rotor magnetic flux of the motor, a current observer calculating a first estimated value of the current flowing through the stator winding of the motor, and an average correction unit performing calculation on the first estimated values of the stator magnetic flux of the motor. The drive quantity adjustment unit calculates a control quantity defining the drive quantity of the motor on the basis of the first estimated values of the stator magnetic flux of the motor.
