      Analysis of Discharge Parameters Affected by Electrode Motion Speed Based on Deep Learning and Traditional Machine Learning

      • 摘要: 静电放电(Electrostatic discharge,ESD)是电子设备安全运行的关键因素,其波形特性受多种参数,如接近速度的显著影响。为此,本文创新性地开发了电极移动速度效应测试仪,采集静电放电波形数据,并利用等宽分箱及多种归一化方法对原始数据进行预处理,提取时域、频域和形态学特征。基于此,本文构建了多种回归预测模型,包括传统机器学习方法(支持向量机(Support vector machine,SVM)、随机森林、决策树和K近邻)以及深度学习方法(长短时记忆神经网络(Long short-term memory neural network,LSTM)、一维卷积神经网络、Transformer、Transformer+LSTM)用于静电放电参数(如峰值与上升速率)的多参数预测。实验结果表明,在基于Min-Max归一化的数据集上,SVM模型在ESD参数预测中表现最佳,决定系数分别达到了0.9913和0.9829,均方误差和平均绝对误差均显著低于其他方法。这表明,SVM在处理小样本和高维数据时具有较高的鲁棒性和泛化能力,而深度学习模型则在自动特征提取方面展现出潜在优势。本文的创新之处在于系统地比较了多种传统与深度学习模型,为静电放电参数预测提供了全新的思路,并为静电防护技术的优化与应用提供了理论依据和实践指导。

         

        Abstract: Electrostatic discharge (ESD) is a key factor in the safe operation of electronic devices, with its waveform characteristics significantly influenced by various parameters, such as approach speed. To address this, the present study innovatively developed an electrode motion speed effect tester to collect ESD waveform data. The raw data were preprocessed using equal-width binning and various normalization methods, and time-domain, frequency-domain, and morphological features were extracted. Based on these features, multiple regression prediction models were constructed, including traditional machine learning methods (support vector machine (SVM), random forest, decision tree, and k-nearest neighbors) as well as deep learning methods (long short-term memory neural network (LSTM), one-dimensional convolutional neural network, Transformer, and Transformer+LSTM) for the multi-parameter prediction of ESD parameters (such as peak value and rising rate). Experimental results indicate that, on the dataset based on Min-Max normalization, the SVM model achieved the best performance in predicting ESD parameters, with determination coefficients of 0.9913 and 0.9829 respectively, and significantly lower mean squared error and mean absolute error compared to other methods. This demonstrates that SVM exhibits high robustness and generalization ability when handling small sample sizes and high-dimensional data, while deep learning models show potential advantages in automatic feature extraction. The innovative aspect of this study lies in its systematic comparison of multiple traditional and deep learning models, providing a novel perspective for ESD parameter prediction and offering theoretical and practical guidance for the optimization and application of electrostatic protection technology.
