Introduction

Gi-Yun Chung is an inventor associated with Atlanta, Georgia, and United Technologies Corporation. His patent work addresses model-based control of gas turbine engines through real-time linearization of an engine model.

Latest Patents

Chung is credited with 1 patent: “Real Time Linearization of a Component-Level Gas Turbine Engine Model for Model-Based Control.” The invention generates an engine operating point from measured parameters using a component-level model. It analytically linearizes the model by calculating the first partial derivatives of each component’s outputs with respect to its inputs and evaluating them at that operating point. The resulting linearized components are combined into a perturbational model, which is inverted to determine control commands from target and measured parameters.

Career Highlights

Chung’s listed patent connects component-level engine modeling with practical control-command calculations. The approach is designed to support model-based gas turbine control by translating measured engine conditions and desired targets into control commands.

Collaborations

Chung’s listed coworkers include Manuj Dhingra and Richard P. Meisner. The patent is associated with United Technologies Corporation.

Conclusion

Gi-Yun Chung’s patent describes a method for linearizing a component-level gas turbine engine model and using it to calculate control commands, highlighting his contribution to model-based engine control.
