Claim 10:
11. A system comprising:
an auto-tune controller; and
one or more sensors coupled to a gas turbine engine, the one or more sensors configured to transmit one or more operating parameters associated with the gas turbine engine to the auto-tune controller, wherein the auto-tune controller comprises a memory and a processor, the memory storing computer-executable instructions that, when executed by the processor, cause the processor to perform operations comprising:
performing a sensitivity step process on a tuning parameter of the gas turbine engine comprising:
monitoring an operating parameter of the gas turbine engine, wherein the gas turbine is operating in a first operational state and the operating parameter has an initial condition;
selecting the tuning parameter of the gas turbine engine for adjustment;
adjusting the selected tuning parameter of the gas turbine engine by a predefined amount to generate a biased tuning parameter, the adjusting comprising applying an incremental bias adjustment to a fuel flow fraction schedule;
adjusting operation of the gas turbine engine to a second operational state based on the biased tuning parameter, wherein the operating parameter has an adjusted condition;
applying the adjusted condition and the initial condition of the operating parameter to a cost function;
determining that the cost function results in a cost function value indicative of a decreased cost; and
writing the incremental bias adjustment and the cost function value to a bias look-up table, wherein the incremental bias adjustment and the cost function value are associated with the selected tuning parameter.
