Abstract:

A fluidic turbine control system provided to interrelate and control first and second turbine operating conditions, has fluidic computing means operable to proportionally combine fluidic input signals which are representative of the differences, if any, between the actual and desired values of said first and second turbine operating conditions and provide therefrom first and second fluidic control signals for control of said first and second turbine operating conditions. In the preferred form the fluidic turbine control systems as applied to a Steam Turbine and extraction pressure to control turbine operation as a function of the extraction pressure and extraction pressure as a function of the turbine operation.
