  • a generator;

    an AC motor;

    a power converter for driving said AC motor using a DC voltage output from said generator; and

    an electric motor controller for controlling said power converter,wherein said motor controller estimates a magnetic flux including a magnetic flux axis component by using a DC voltage predicted value predicting a change in said DC voltage, determines a current command based on a torque command and said estimated magnetic flux, and controls said power converter based on said current command.
