BACKGROUND

1. Field

The present disclosure relates generally to system controllers and, more particularly, to a system controller for a series hybrid powertrain that may be used, at least in part, to facilitate and/or support aircraft propulsion, for example.

2. Information

Typically, in a conventional aircraft, performance of an internal combustion engine (ICE), such as a gas turbine engine (e.g., a turbofan, turbojet, etc.), for example, is controlled by a dedicated propulsion control system, such as a Full Authority Digital Engine Control (FADEC) system. FADEC is typically a digital computer with a single or multiple channel configuration that receives and analyzes a limited number of information inputs, such as from a throttle lever, autopilot, engine, associated sensors, etc. and controls a fuel flow rate (e.g., air/fuel ratio, etc.) to the ICE for an appropriate thrust. In a hybrid electric aircraft, however, for powertrain control, a system controller may be employed. Thus, greater flexibility and/or variety of approaches for implementing a system controller, such as to control operation of a propulsion powertrain for a hybrid electric aircraft, for example, may, therefore, be desirable.
