| Popis: | In order to improve the reliability and safety of satellite power system, the concept of health management is introduced to the research of health state assessment about satellite power supply. Considering the complex characteristics of satellite power system, a health state assessment method based on fuzzy judgment and variable weight layered evaluation is proposed and applied to the assessment of satellite power system. First, the fuzzy comprehensive evaluation method is used to quantify the influence degree of fault modes on the system and obtain the objective corresponding health degree. The method also combines analytic hierarchy process (AHP) with variable weight synthesis to solve variable weights and calculate health degree of the system step by step, which conducts real-time health state assessment for satellite power system. And then, the calculation results are divided into healthy, good, attentive, deteriorative, and morbid 5 levels to characterize the health states of the evaluation object. Finally, the applicability and validity of the method are verified by the concrete calculation example. |
