介绍了广义频率响应函数（ＧＦＲＦ）的基本原理和基本性质，研究了基于ＧＦＲＦ模型非参数模型的辨识算法，并尝试把ＧＦＲＦ理论应用于非线性系统的故障诊断，探讨了从ＧＦＲＦ谱中提取故障特征信息的方法。经实际使用，取得了较为显著的成效。
The basic principle and basic properties of generalized frequency response function (GFRF) are introduced. The identification algorithm of non-parametric model based on GFRF model is studied. At the same time, GFRF theory is applied to the fault diagnosis of nonlinear system. The problem of extracting fault from GFRF spectrum Method of characteristic information. After actual use, has achieved more significant results.
