Methods and systems for managing power of an engine

A power management system for online power management of an engine, said power management system comprising:

• a baseline power management component configured to receive at least one data input from an engine control system operating on a first bandwidth, wherein said baseline power management component is configured to operate on a second bandwidth;
• and
• a model predictive control configured to:
• predict an engine operating condition over a desired future horizon using the at least one data input and a closed-loop model of the engine;
• determine an optimal engine power management based on the prediction;
• solve a constrained optimization for a desired optimization objective;
• and
• output the optimal engine power management.

A gas turbine engine for use in an aircraft, said gas turbine engine comprising:

• at least one sensor configured to sense an engine parameter and to generate a sensor input representing the engine parameter;
• an engine control system operating on a first bandwidth and configured to control said gas turbine engine;
• and
• a power management system for online power management of said gas turbine engine, said power management system comprising:
• a baseline power management component configured to operate on a second bandwidth and to receive at least one data input from the engine control system;
• and
• a model predictive control configured to:
• predict an engine operating condition over a future horizon using the at least one data input and a closed-loop engine model;
• determine an optimal engine control based on the prediction;
• solve a constrained optimization for a desired optimization objective;
• and
• output the optimal engine power management.
