Research On Frequency-Domain Kernel Identification Of Volterra Series

摘要

In this paper, the identification method of Volterra series frequency-domain kernel is introduced from two aspects: parameter identification and non-parameter identification, then gives prospect. Volterra series theory has been applied and developed in recent years, becomes one of the most effective tools for non-linear system analysis and modeling. The kernel of Volterra series can reflect the fault characteristics well. Therefore the problem of kernel identification has been the focus of research. Among them, the frequency-domain kernel identification is concerned because of many advantages, such as strong robustness, no need to determine the memory length and so on.
