[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the public implementation manners of the present invention in detail with reference to the accompanying drawings.
[0049] Aiming at the specific characteristics of non-complete failure faults, the present invention proposes a novel quantification method by introducing Bhattacharyachian distance and using the principle of distance similarity, and realizes the quantification of the diagnosability of non-complete failure faults under the influence of uncertainty. It not only provides a possible solution and idea for maximizing the autonomous fault diagnosis capability of my country's new generation of deep space exploration spacecraft: moving the focus of improving the spacecraft's on-orbit fault diagnosis capability to the design stage; The engineering practicality of the integrated design of spacecraft model functions, performance, reliabil...
