这是一篇基于matlab的电力系统仿真组件matpower的使用手册。主要介绍了matpower软件的功能以及它的具体操作。(This is matpower user s manuala, power system components of matlab-based simulation. It Introduces matpower software functionality as well as its specific operation.)

几个解耦控制系统的Simulink模型，用过还行。共享一下。(Several decoupling control system Simulink model, used also OK. Sharing about.)

本文提出了一种适用于低轨卫异扩频通信系统的多普勒频移快捕方法.该方法基于数字匹配滤波器及自动频率控制环路_利用数字匹配滤波器的囚码快捕特性及其输出主相关峰值对频偏的敏感性，缩短多普勒频移的 捕获时间.论文首先推导了多普勒频移的平均捕获时间表达式，然后根据数值分析结果得到了准最佳捕获判决策略，最后通过比较验证了该快捕方法相对于传统串行捕获方法在性能上的提高. (This paper presents a low-orbit health for different spread spectrum communication system fast catching the Doppler shift method, which based on digital matched filter and automatic frequency control loop _ prisoners using digital matched filter code features rapid acquisition and the output of the main correlation peak frequency deviation of the sensitivity of the Doppler frequency shift to shorten acquisition time. paper first derive the mean Doppler shift acquisition time expression, then the numerical results obtained quasi-optimal capture decision strategies, and finally verified by comparing with the rapid acquisition method to capture the traditional method of serial improvement in performance.)

有关 层次分析法的 小程序 有需要下载 请下载 (The analytic hierarchy process (ahp) of small programs)

异步电机simulink仿真程序，有需要的可以下载交流，(PID control)

i need matlab codes for this documents on electronics

It is a very good MATLAB book.
