When some new-type sensors are subjected electromagnetic interference (EMI), the traditional standard can no longer serve as the guidance for their EMI protection. Therefore, it is necessary to evaluate the complexity of the new sensing equipment's suffering from electromagnetic interference. A hybrid method of feature extraction and complexity evaluation of Electromagnetic Interference signals based on generalised correntropy criterion (GCC) is proposed. First, a variational mode decomposition algorithm for adaptive extraction of decomposed signals is constructed using GCC, and Generalised S-transform is used for processing and reorganisation. Then, according to the time-frequency space model, a new quantitative evaluation criterion interference factor is proposed, which overcomes the shortcomings of the traditional qualitative classification and the inability to solve the cross classification of indicators. Then, the Gated Recurrent Unit is introduced, and the GCC-GRU evaluation model with GCC as the loss function is derived. The authors conduct EMI tests and measured signal evaluation with Medium Voltage and High Voltage switches, and the results show that the method proposed is correct and effective.

基于特征提取和GCC-GRU网络的高压开关电磁干扰复杂度评估方法

当一些新型传感器受到电磁干扰（EMI）时，传统标准就无法再作为其EMI防护的指导。因此，有必要评估新型传感设备遭受电磁干扰的复杂程度。提出了一种基于广义相关熵准则（GCC）的电磁干扰信号特征提取和复杂度评估的混合方法。首先，利用GCC构建了自适应提取分解信号的变分模式分解算法，并使用广义S变换进行处理和重组。然后，根据时频空间模型，提出了一种新的定量评价标准干扰因子，克服了传统定性分类和无法解决指标交叉分类的缺点。然后引入Gated Recurrent Unit，推导了以GCC为损失函数的GCC-GRU评估模型。作者对中压和高压开关进行了EMI测试和测量信号评估，结果表明所提出的方法是正确和有效的。
