1. A method for controlling a turbogenerator, comprising:

  • operating the turbogenerator at a selected speed to provide a selected amount of power;

    providing fuel to the turbogenerator to maintain a turbine exhaust temperature at a first selected value;

    reducing the turbogenerator speed to provide a reduced amount of power;

    providing fuel to the turbogenerator to maintain the turbine exhaust temperature at a second selected value higher than the first selected value for a selected period of time; and

    gradually increasing the amount of fuel provided to the turbogenerator over the selected period of time to maintain the turbine exhaust temperature at the second selected value.
