Abstract

The invention relates to a field line coupling uncertainty quantification and global sensitivity calculation method. An adaptive hyperbolic truncation scheme is combined with a minimum angle regression method to carry out sparse processing on a generalized chaotic polynomial, an agent model is established to analyze the uncertainty problem of the radiation sensitivity of a multi-conductor transmission line, and the global sensitivity of an input variable is analyzed by a global sensitivity analysis method. According to the scheme, on the premise that the calculation precision is guaranteed, related statistical characteristic parameters and the like in the uncertainty problem of the radiation sensitivity of the multi-conductor transmission line can be rapidly and accurately calculated, andthe scheme is effective when the total sensitivity index and the first-order sensitivity index of the radiation sensitivity of the multi-conductor transmission line are calculated.

Description

technical field [0001] The invention relates to the field of radiation sensitivity of multi-conductor transmission lines, in particular to a field line coupling uncertainty quantification and global sensitivity calculation method. Background technique [0002] With the continuous development of science and technology, various electrical systems and electronic equipment are widely used in real life, resulting in an increasingly complex electromagnetic environment for electrical equipment. As a carrier for transmitting electric energy and signals, transmission lines are an indispensable part of electrical and electronic equipment; due to the complexity of the electromagnetic environment, the problem of electromagnetic compatibility of transmission lines has gradually become more and more serious. Radiation sensitivity, as an important issue in electromagnetic compatibility, has been paid more and more attention by researchers. [0003] Due to the possible changes of electrica...
