  • MexCDF-toolbox
    我看到网上很多雷达信号处理的人都想从IPIX网站上下载数据,可是却没有MexCDF toolbox ,今天我把它上载,百分之白能用,里面有详细的安装步骤,可以在matlab7到matlab2012上使用。(I see online many radar signal processing wants to download data from the IPIX website, but did not MexCDF toolbox I upload per cent of white can be used, which has detailed installation steps, in matlab7 to matlab2012 to use.)

    在风力发电的模拟控制系统中,风速的模拟是一个重要的环节,而正确的风速模型不仅能够很好的 反应实际风速变化情况,而且能够给风力发电系统研究提供正确的源参数。本文用 Matlab/Simulink建立了风速组合数学模型,该模型将风速分为基本风速、阵风、渐变风速和组合风速4部分,仿真结果表明该模型能够理想的反应实际风速。(In the simulation control system of wind power generation, wind speed simulation is an important link, and the correct wind speed model can not only reflect the actual wind speed changes, but also provide the correct source parameters for wind power system research. In this paper, a combined mathematical model of wind speed is established by using MATLAB / Simulink. The model divides the wind speed into four parts: basic wind speed, gust wind, gradual wind speed and combined wind speed. The simulation results show that the model can reflect the actual wind speed perfectly.)
