( 4 ) since there is no perfect theoretical guide, the characteristics of orthogonal wavelet, semi - orthogonal wavelet and biorthogonal wavelet in signal decomposition and reconstruction are compared, and the conclusion of the study demonstrates that semi - orthogonal wavelet is a good wavelet for fault diagnosis in tilting control system of tilting train. a new approach is presented for deciding the fault threshold. ( 5 ) a generalized wavelet neural network is put forward by integrating wavelet analysis with neural network
（ 4 ）針對小波基的選擇缺乏完善理論指導的實際情況，通過對常用的正交、半正交、雙正交小波基提取信號特性的比較，確定出了適合擺式列車傾擺控制系統故障診斷的小波基? ?半正交小波基，並提出了一種新的確定故障檢測閾值的方法，可以快速地檢測出故障發生時刻。
