Koopman-Based Nonlinear Identification and Model Predictive Control of a Turbofan Engine
David Grasev
This paper investigates Koopman operator-based approaches for multivariable control of a two-spool turbofan engine. A physics-based component-level model is developed to generate t…

Spatially Aware Dictionary-Free Koopman Eigenfunction Identification for Modeling and Control
David Grasev
A spatially aware dictionary-free eigenfunction discovery (SADFED) framework is proposed for identification of low-rank Koopman models from data without prescribing a lifting dicti…

Koopman Eigenfunction-Based Identification and Optimal Nonlinear Control of Turbojet Engine
David Grasev
Gas turbine engines are complex and highly nonlinear dynamical systems. Deriving their physics-based models can be challenging because it requires performance characteristics that…
