1. A method for controlling a rotational speed of a rotor or shaft of a turbogenerator, the method comprising:

  • establishing a lower threshold and a higher threshold for a speed of a rotor or shaft of a turbogenerator;

    determining speed data or a speed signal for a rotor or shaft associated with a turbogenerator; and

    adjusting a voltage level associated with a direct current bus within a target voltage range if the speed data or speed signal indicates that the speed is above the higher threshold or below the lower threshold.
