description One embodiment of the invention provides a turbine control system that adjusts the control thresholds of two-position valves, which provide propellant to the turbine, based on turbine load so as to compensate for increased turbine speed overshoot at low load and the increased turbine speed undershoot at high load. These two-position on-off modulated valves are used in a bang-bang (fully open or fully closed) regulation scheme to eliminate or minimize speed droop by using variable speed bounds implemented as a function of load.
