An anti-radiation evaluation method for satellite power system based on quantification of margins and uncertaities

Satellite power system is the key component of the satellite system. Properly anti-radiation evaluation is an important basis for system design improvement, maintenance and health management. Traditional model-based methods or statistical methods are difficult to treat such problems due to all kinds of uncertainties and the lack of data. This paper proposed a quantitative anti-radiation evaluation method on the basis of quantification of margins and uncertainties(QMU) and combined the data and modeling. Model calibration, uncertainty analysis and other approaches are used to calculate the performance indices and assess whether it meets the expected requirements, which is crucial to the evaluation. In the application of a satellite power system evaluation, it demonstrates the efficiency of this method. Relevant issues for further research are concluded at the end, to be further studied and resolved.
