Testing Uncertainty Assessment of the Electromagnetic Interference Emission Equipment of the Digital Twins

Abstract

AbstractCurrently, the main problem highlighted by specialists during digital twins testing relates to ensuring the test results reliability. The aim of this article is to assess the uncertainty of testing digital product twins for compliance with electromagnetic compatibility standards. In this regard, the authors developed an automated system model for testing digital product twins for compliance with electromagnetic compatibility standards. This model is applicable to digital twins of any electronic products that are capable of creating electromagnetic interference. It can be also used in cases when the quality of operation depends on the effect of external electromagnetic interference. Real system simplifications and abstractions are used in modelling, and therefore it is necessary to ensure that the results of the simulation can be used in decision-making on the compliance of products with EMC requirements. The analysis of the fundamental works on assessing of testing product digital twins uncertainty allowed to estimate the most probable budget of uncertainties that can affect the result reliability of an automated system for testing digital product twins for compliance with electromagnetic compatibility standards. Uncertainty assessment was carried out using the methods proposed in the basic international EMC standards (CISPR 16-4-2: 2011, ISO / IEC 17025). The uncertainty estimation algorithm proposed by the authors can be applied by product manufacturers that strive to increase the test results reliability of digital twins for EMC. This is of particular importance to solve technical security problems in areas such as power industry, electronics, transport security systems and weapons.KeywordsDigital twinsElectromagnetic interference emissionTest reliabilityDigital test model
