Representative Interconnect Diagnosis Algorithm Analysis of Solving Fault Syndrome Aliasing and Confounding

为提高算法研究以及工程应用人员对现有算法的总体把控和算法选择的能力,在综述现有算法的基础上,找出3类最具代表性的互连诊断算法——基本算法、抗误判算法和对角独立算法;并给出该3类算法的抗误判和抗混淆能力结论:抗误判算法解决了故障征兆误判问题,对角独立算法可以大大地降低故障征兆混淆率,为故障诊断算法的选择寻找出了理论依据.

In order to improve algorithm research and engineering application staff＇s overall control and choice guidance of the algorithm, this paper identifies three most representative interconnect diagnosis algorithms： the basic algorithm, anti-aliasing algorithm and diagonal independent algorithm on the basis of the overview of the existing algorithms. Anti-aliasing algorithm solves the problem of fault syndrome aliasing. Diagonal independent algorithm can greatly reduce the fault syndrome confounding rate. The characteristic of each algorithm provides the theoretical guidance for the choice of fault diagnosis algorithm.
