Abstract: A system (10) includes a controller (18) including a processor (24) configured to execute a program stored in a memory of the controller to generate and transmit a first output (68) comprising a total flow demand value (30) to a plurality of valves (26,27,28,29) communicatively coupled to the controller. Each of the plurality of valves (26,27,28,29) is configured to receive a respective portion of the total flow demand value (30). The processor (24) is configured to receive an input indicative of a decoupling of a first valve (27) of the plurality of valves and to generate a second output (69) based at least in part on the first output (68) and a first operational characteristic of the first valve (27). The second output (69) is configured to vary a second operational characteristic of a second valve (26,28,29) of the plurality of valves to maintain the total flow demand value (30).

Abstract: A system for controlling fluid flow in a turbine that includes at least one flow valve (106) configured to regulate fluid intake through the turbine. The system further includes a control system (120) 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 (202). Convert the percent value flow command to a unit value flow command (216). Determine a unit value stroke command (206) based on the unit value flow command. The processor is further configured to control a position of the at least one flow valve (106) to the unit value stroke command.
