| 摘 要： | 设计了一种基于粗糙集与支持向量基的乳腺肿瘤图像识别方法.其基本思想是首先对图片进行降噪预处理,接着提取纹理和形状特征构成表征医学图像的特征矢量,然后将特征离散归一化处理,再用粗集方法进行特征属性约简,最后利用支持向量基进行识别.结果表明,该方法取得了比较理想的识别效果.

| Abstract: | In order to describe the output characteristics of a vertical axis wind turbine, the wind speed model, drivesystem and speed control system of a vertical-axis wind turbine are established in MATLAB/SIMULINK. Particularly, takinga 5KW vertical axis wind turbine as example, the power coefficients under the different tip speed ratio are received by usingDouble-Multiple Streamtube （DMS） model. Then the data is imported into MATLAB, and the mathematical model of the5 KW vertical axis wind turbine rotor is obtained by using the curve fitting toolbox, thus the SIMULINK model is built. Laterthe wind turbine model is formed by these above models and other models. Some operation parameters of wind turbine aregiven, and the data for analysis is received. Through the simulation study, MATLAB/SIMULINK can better simulate theoverall performance of a wind turbine from wind turbines to the drive system, which provides a reference for the futureresearch of the overall performance of vertical axis wind turbines. |
