Abstract
Methods and systems for method for managing a hybrid-electric powerplant (HEP) comprising a thermal engine and an electric motor are described. The method comprises transmitting a thermal power command to the thermal engine to generate a thermal power output; transmitting an electric power command to the electric motor to generate an electric power output; comparing the thermal power output to the thermal power command and the electric power output to the electric power command; detecting a fault when the thermal power output deviates from the thermal power command or when the electric power output deviates from the electric power command; and accommodating the fault by modulating the thermal power command in response to a deviation in the electric power output and modulating the electric power command in response to a deviation in the thermal power output.
