1. A system comprising:

  • a turbine generator;

    one or more two-position valves to provide one or more propellants to the turbine generator; and

    a controller coupled to the one or more two-position valves, the controller configured todetermine an operating speed of the turbine generator,compare the operating speed to a reference speed,if the operating speed is greater than the reference speed then the one or more two-position valves are fully closed to reduce the speed of the turbine generator,if the operating speed is less than the reference speed then the one or more two-position valves are fully opened to increase the speed of the turbine generator,wherein the reference speed varies as a function of load on the turbine generator to decrease speed droop at increased loads.
