A system for controlling fluid flow in a turbine that includes at least one flow valve configured to regulate fluid intake through the turbine. The system further includes a control system operatively coupled to the at least one flow valve. The control system includes at least one processor configured to receive a percent value flow command. Convert the percent value flow command to a unit value flow command. Determine a unit value stroke command based on the unit value flow command. The processor is further configured to control a position of the at least one flow valve to the unit value stroke command.
