Claim Text:
1. A system, comprising: a controller configured to control one or more parameters of a gas turbine engine based on a feedback and a predicted lifespan of one or more components of the gas turbine engine, wherein the controller comprises instructions disposed on a non-transitory, machine readable medium, wherein the instructions are configured to: operate the gas turbine engine; determine a base power output, a base heat rate, or a combination thereof based on new and clean operation of the gas turbine engine at base load; obtain a corrective parameter; determine a target power output, a target heat rate, or a combination thereof based at least in part on the base power output, the base heat rate, or a combination thereof and the corrective parameter; monitor a power output, a heat rate, or a combination thereof of the gas turbine engine; compare the power output to the target power output, compare the heat rate to the target heat rate, or a combination thereof; adjust the one or more parameters of the gas turbine engine such that a difference between the power output and the target power output, the heat rate and the target heat rate, or a combination thereof is less than a threshold value, wherein the difference between the power output and the target power output, the heat rate and the target heat rate, or the combination thereof is caused at least partially by degradation and/or fouling of the gas turbine engine; determine at least one base output value based on the base load of the gas turbine engine; determine at least one predicted lifespan of at least one component of the gas turbine engine at the base load; determine at least one target lifespan of one or more components of the gas turbine engine; determine at least one calculated output value based at least in part on the at least one base output value and the at least one target lifespan; monitor at least one output value of the gas turbine engine; compare the at least one output value to the at least one calculated output value; and adjust at least one operating condition of the gas turbine engine such that at least one difference between the at least one output value and the at least one calculated output value is less than at least one threshold value.
