Abstract
A method for a hybrid electric propulsion (HEP) system includes utilizing a soft actor-critic agent, which includes at least one neural network, and a control barrier function (CBF) filter to obtain a power splitting profile for an HEP system. The power splitting profile includes an electric motor power for an electric motor of the HEP system and a gas turbine power for a gas turbine of the HEP system. The electric motor power and gas turbine power collectively provide a combined HEP output power. The method also includes, during a flight of an aircraft that includes the HEP system, performing an output action for the HEP system based on the power splitting profile. The utilizing is performed based on a predefined fuel consumption objective and a state of charge of at least one battery that powers the electric motor. A system for a HEP system is also disclosed.
