Abstract
Abstract A method of designing the operations and controls of a aircraft gas turbine engine (10) includes generating an operations model for the gas turbine include at least one objective function, defining operations and control constraints for the operations model of the gas turbine, and providing an online dynamic optimizer/controller that dynamically optimizes and controls operation of the gas turbine using model predictive control based on the operations model and the operations and control constraints using an Extended Kalman Filter for estimation.
