Claim 0:
1. A turbine control system, comprising:
a speed probe detecting a speed of a turbine;
a turbine valve controlling a flow of a fluid or a gas to or from the turbine;
a controller in communication with the speed probe and the turbine valve, the controller receiving a speed signal from the speed probe, and the controller sending a first signal and a second signal to the turbine valve, the first signal comprising a valve position command to change a position of the turbine valve in response to the speed signal and the second signal comprising a support function that does not command a change in position of the turbine valve in response to the speed signal,
wherein the controller outputs the first signal at a faster rate than the second signal.
