By using the steepest descent rule, the estimated second-truncated Volterra kernel parameters can be obtained after the object function converged. Based on the above results, the geometric assignment of kernel parameter vector corresponding to particular fault or normal operation, which is lies in a fixed and fault-specified direction in the parameter space, was used to fault diagnosis and Fault Isolation.

第四章针对起动发电机系统在起动过程具有较强的非线性特性，利用非线性volterra建模后获取的核参数向量来表征起动发电机的正常工作及各种故障模型，而核参数求值过程中快速收敛，有利于实现故障的快速、准确诊断与故障类型分离。

The data analysis shows that: 1 different texture parameters have a clear scattered distribution, 2 the main direction of texture is the direction represented by the maximum parameter of Gauss-MRF parameters, and 3 for those samples basing the same main direction, the finer the texture is, the greater the corresponding parameter is, and the smaller the other parameters are; and the higher the order of Gauss-MRF is, the more clearly the texture is described.

数据分析表明，各不同纹理特征参数之间具有明显的分布性；Gauss-MRF参数值最大的参数所表示的纹理集聚为向为纹理的主方向；对于纹理主方向相同的样本，纹理越细致，其相应参数越大，而其他参数越小；Gauss-MRF阶数越高，纹理描述越细致：在2阶Gauss-MRF模型情况下，弦切纹理的B1参数大于径切纹理的B1；弦切纹理的B2、B3、B4分别小于径切纹理的B2、B3、B4。
