基于梯度算法的永磁伺服系统惯量辨识性能研究(Recognition properties of inertia permanent magnet servo system based on the gradient algorithm)

说明：  对标准卡尔曼滤波方法中野值对其滤波精度的影响，提出了基于M估计的野值 处理方法。这种方法不仅可以去除单个野值的影响，而且在野值成片出现时还能很好地保持滤波 稳定性。通过仿真验证了该方法的有效性。(Their filtering accuracy on the standard Kalman filtering method outliers, outliers based on M-estimation approach. This method can not only remove the impact of individual outliers, and opposition values ​ ​ into the film appears to keep the filter can be very stability. The effectiveness of the method is verified by simulation.)

提供瑞利信道衰减模型的matlab源代码。(Rayleigh channel attenuation model matlab source code.)

说明：  A New Fuzzy Fault Locator for Series Compensated Transmission Lines

a easy back propagation example done in matlab,

经验模态分解(EMD)的Matlab程序包(Empirical Mode Decomposition (EMD) of the Matlab package)

灰色关联分析的标准化matlab源程序，能算出给定样本数据的关联性(Standardization of the gray relational analysis matlab source, is able to calculate the correlation of data in a given sample)

1:对于所有等级的隶属度之和为1。 2：输出结果随某个变量的增大而qdh1的结果呈现出单调递增或递减 3:最后的等级出[0.2 0 0 0.8]这种情况是正常的，和可拓评判中的对于等级的距离的概念是不一样的。 只表现有变量是属于0.2这个等级的。

手写数字识别程序，matlab运行前，先点击安装控件，内部有三种模型，GUI形式，使用方便(Handwritten numeral recognition program, matlab run before, first click on the installation of control, there are three kinds of models, GUI form, the use of convenience)

用矩量法计算细线天线的场分布，允许用户自行制定天线长度等参数．(Using moment method calculation of the field distribution of thin wire antennas, allowing users to establish their own parameters such as antenna length.)
