摘要

中文摘要: 为实现模拟电路参数辨识和降低故障诊断成本，提出一种基于矩阵扰动理论的模拟电路故障诊断和参数辨识方法。该方法不同于基于数字信号处理（DSP）与人工智能的方法，而是从代数观点出发，以被测电路响应矩阵的本征值随被诊断器件参数的变化而变化的对应关系为基础，建立故障模型。该模型将故障检测，故障定位和参数辨识一体化处理，具有易于工程实施的优点。实验结果表明该方法的计算时间开销小，可降低测试成本，故障定位和故障参数辨识精度高，实验结果中的最大辨识误差为2.35%。

Abstract

Abstract:In order to achieve the parameter identification and reduce the diagnosis cost of analog circuit

Unlike the methods based on digital signal processing (DSP) or artificial intelligence

a new method based on matrix perturbation theory for analog circuit fault diagnosis is proposed. in the view of algebraic theories

And by analyzing the problems of fault modeling

fault feature extraction and the tolerance handling in fault diagnosis for analog circuit

this paper attempts to construct a theoretical framework that integrates fault detection

fault location and parameter identification based on the relationship between the device parameters and response matrix eigenvalues. By comparing the proposed model with its counterparts

the experimental results show that the proposed model outperforms its counterparts in the respect of computational cost and fault parameter identification. In two experiments

the identification errors are less than 2.35%.
