Claim Text:
1. A method for adaptively controlling a gas turbine engine, comprising: generating model parameter data as a function of prediction error data, which model parameter data includes at least one model parameter that accounts for off-nominal operation of the engine and at least one model parameter that accounts for nominal operation of the engine, wherein the engine is configured for an airplane propulsion system; at least partially compensating an on-board model for the prediction error data using the model parameter data; generating model term data using the on-board model, wherein the on-board model includes at least one model term that accounts for the off-nominal operation of the engine, the model term comprises a mathematical equation, and the model term data comprises one or more terms of the mathematical equation; respectively updating one or more model parameters and one or more model terms of a model-based control algorithm with the model parameter data and model term data; and generating one or more effector signals using the model-based control algorithm.
