Abstract
A method can include perturbing an electric motor of a hybrid powerplant having the electric motor and a fuel powered engine. The method can include measuring a frequency response of the powerplant due to the perturbing of the electric motor to determine a health of the powerplant and/or one or more components thereof.
Claims17
A method performed by a health module of a health diagnostic system, comprising the steps of:
- perturbing an electric motor of a hybrid powerplant having the electric motor and a fuel powered engine;
- measuring a frequency response of the powerplant due to the perturbing of the electric motor to determine a health of the powerplant and/or one or more components thereof;
- and
- comparing an expected frequency response to the measured frequency response to determine a health of the powerplant and/or the one or more components thereof.
