Zusammenfassung:Certain embodiments of the invention may include systems and methods for providing unchoked control of gas turbine fuel control valves. According to an exemplary embodiment of the invention, a method is provided for active control of a gas flow control valve (146). The method may include receiving a desired fuel command (250) and an inlet pressure parameter (224), and based at least in part on the inlet pressure parameter (224) determining a gas flow gain (244). The method may also include determining a valve flow coefficient (258) based at least in part on the desired fuel command (250) and the gas flow gain (244), and controlling the gas flow control valve (146) based at least in part on the valve flow coefficient (258).
