说明：  计算阶次分析的案例，需要转速信号进行角度域重采样。(In the case of order analysis, the angle domain resampling of speed signal is needed.)

光伏并网系统单相逆变器电压前馈电流控制，基于matlab 7.3 。(photovotaic grid-connected system single-phase inverter voltage feed forward current control,based on matlab 7.3)

interior permanent magnet synchronous machine speed control using pi controller

In the planning stage of a GNSS-measurement campaign it is useful to compute several design para-meters in order to decide how, when and where to carry out the measurements. The MATLAB user interface VISUAL.M enables you to compute the design parameters for any system design.

灰色模型（GM)。如果一个系统具有层次、结构关系的模糊性，动态变化的随机性，指标数据的不完备或不确定性，则称这些特性为灰色性。具有灰色性的系统称为灰色系统。在灰色系统理论中，利用较少的或不确切的表示灰色系统行为特征的原始数据序列作生成变换后建立的，用以描述灰色系统内部事物连续变化过程的模型，称为灰色模型，简称GM模型。(GM 1 to 1)

透视变换的程序，一个很好的透视变换程序，希望大家下载(Perspective transformation process, a very good perspective transformation process, I hope you download)

此程序是对无刷直流电机的反电势进行仿真的！(This program is a brushless DC motor to simulate the EMF!)

对轴承振动信号进行各种时频分析，以获取相应的时频域分布图，用于轴承故障诊断(bearing vibration signal time-frequency analysis to obtain the corresponding time-frequency domain distribution for bearing fault diagnosis )

本方法是对二维医学图像实现的Walsh变换，属于预处理范围，为下一步的图像分割，配准等打下基础(This method is the realization of two-dimensional medical images of the Walsh transform, belong to the scope of pre-treatment, for the next phase of image segmentation, registration, etc. to lay the groundwork)
