Adaptive model predictive control for hybrid electric propulsion

A hybrid electric propulsion system comprising:

• a gas turbine engine;
• an electrical power system;
• a mechanical power transmission operably coupled between the gas turbine engine and the electrical power system;
• a plurality of hybrid electric system control effectors operable to control a plurality of states of one or more the gas turbine engine and the electrical power system;
• and
• means for controlling the hybrid electric system control effectors based on a model predictive control that is dynamically updated during operation of the hybrid electric propulsion system.

A method for controlling a hybrid electric propulsion system, the method comprising:

• determining, by a controller, an estimate of a plurality of hybrid electric propulsion system parameters based on a composite system model and a plurality of sensor data;
• determining, by the controller, a model predictive control state and a prediction based on the hybrid electric propulsion system parameters and the composite system model;
• determining, by the controller, a model predictive control optimization for a plurality of hybrid electric system control effectors based on the model predictive control state and the prediction using a plurality of reduced-order partitions of the composite system model;
• and
• actuating, by the controller, the hybrid electric system control effectors based on the model predictive control optimization.
