Hybrid electric propulsion system load share

A system comprising a first engine, a second engine, a first electric machine coupled to the first engine, a second electric machine coupled to the first engine or the second engine, and a controller, the controller including memory and one or more processors, the memory storing instructions that when executed by the one or more processors cause the system to perform the following:

• receive data indicative of a first engine operating parameter, a second engine operating parameter, or both;
• determine a first engine operating parameter margin, a second parameter operating margin, or both;
• determine a load share for the first engine, the second engine, or both, or between the first engine and the second engine based on the first engine operating parameter margin, the second engine operating parameter margin, or both;
• and transfer a first amount of power to or from the first electric machine and a second amount of power to or from the second electric machine in response to the determined load share;
• wherein the second electric machine is coupled to the second engine, and wherein the instructions when executed by the one or more processors further cause the system to perform:
• receive data indicative of a first engine operating parameter of the first engine while operating the first engine at a first power level;
• receive data indicative of a second engine operating parameter of the second engine while operating the second engine at the first power level;
• and determine the first engine operating parameter margin and the second parameter operating margin.
