Stranded wire RLCG parameter extraction method based on BAS-BP algorithm

Abstract

The invention discloses a stranded wire RLCG parameter extraction method based on a BAS-BP algorithm. According to the stranded wire RLCG parameter extraction method, a novel stranded wire RLCG parameter extraction network model is established based on a beetle antennae search algorithm (BAS) and a BP neural network algorithm. The stranded wire RLCG parameter extraction method can utilize the network to extract a high-precision RLCG electromagnetic parameter matrix at any position of a stranded wire, and comprises the following steps of: firstly, establishing a stranded wire model and extracting a parameter sample by virtue of an ANSYSQ3D software platform; carrying out sample processing after a space structure of the stranded wire is analyzed; importing the processed data into a BAS-BP neural network model; and finally, acquiring an optimal extraction network through training and testing. The existing transmission line RLCG parameter extraction methods are mostly based on a numericalalgorithm, lack of processing capacity for stranded wire type non-uniform transmission lines, is based on the intelligent algorithms, has the advantages of high precision, high efficiency and the likecompared with a traditional method, has no special requirements for wire types, and can better solve the problem of extraction of stranded wire electromagnetic parameters.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic interference, and in particular relates to a method for extracting twisted wire RLCG parameters based on a BAS-BP algorithm. Background technique [0002] The twisted wire is realized by twisting the single wire around the twisted wire shaft at an equal angular velocity and moving the twisted wire forward at a uniform speed. big occasion. The use of twisted wires can reduce the operating temperature. Compared with single-strand wires with the same cross-sectional area, twisted wires have higher mechanical properties and flexibility. As early as 1960, scholars began to conduct corresponding research on the internal crosstalk of twisted-pair wires. , There are also a large number of literatures that have studied the electromagnetic interference of field coupling to twisted wires, but the research on the internal crosstalk of multi-core twisted wires is still less.
