Abstract: A non-transitory computer-readable medium storing computer executable code that includes instructions to receive a signal representative of a gas turbine firing temperature. The code further includes instructions to convert the signal to an actuator signal to actuate a fuel valve supplying fuel to the gas turbine by following a first reference function. The first reference function includes a first boundary function, a second boundary function, or a combination thereof. The first boundary function maps a first value to a first temperature and the second boundary function maps a second value to a second temperature.

Abstract: A method of tuning a gas turbine includes receiving a first plurality of operating parameters as the gas turbine engine is operated at a first operating state. Further, the method includes operating the gas turbine engine at a second operating state to measure a second plurality of operating parameters at the second operating state. In addition, the method includes operating the gas turbine engine at a third operating state to measure a third plurality of operating parameters at the third operating state, wherein the first, second, and third operating states are different from each other. Additionally, the method includes generating a correction factor based on the first, second, and third plurality of operating parameters. The method also includes adjusting the operation of the gas turbine engine based on the correction factor.
