摘要： A rotating machine control device for controlling a rotating machine having a stator winding and a field winding includes a current command generation unit which generates a current command value on the basis of the temperature of the rotating machine. The current command generation unit includes a constraint condition setting unit which calculates a constraint condition on the basis of a torque command, stator winding voltage, stator winding current, and field winding current, an optimization calculation unit which calculates and outputs the current command value, using the constraint condition and an evaluation function, and a constraint condition update unit which updates the constraint condition on the basis of the temperature of the rotating machine. The current command generation unit calculates and outputs the current command value, using the updated constraint condition.

摘要： This motor control device controls a motor having a first stator winding, a second stator winding, and a field winding whose response to a current command is slower than those of the first stator winding and the second stator winding, and includes: a parameter acquisition unit which acquires motor state data and a motor parameter corresponding to the motor state data; and a current command calculation unit which calculates current commands for the windings on the basis of a torque command for the motor and the motor parameter. The current command calculation unit includes a response delay reproduction unit which reproduces response delay of field winding current in a field winding current command, and calculates a first stator winding current command and a second stator winding current command, using the field winding current command in which the response delay is reproduced.
