结构分析的有限元法与MATLAB程序设计-源代码

说明：  笼型异步发电机组模型，包括风力机，发电机等，可运行(Detailed model and grid-connected control of doubly-fed fan can be operated.)

说明：  百分百高仿小说下载站源码，减轻大家仿站的难度(100% high imitation novel download site source code, reduce the difficulty of everyone imitation station)

书中详细介绍了地震勘探中的一些非常重要的数值计算方法，并用matlab将其算法实现，有助于理解地震勘探的基本原理 。(The book details some of the most important numerical calculation methods in seismic exploration, and uses Matlab to implement its algorithm, which is helpful to understand the basic principles of seismic exploration.)

包括最小二乘法、SVM、神经网络、1_k近邻法,本科毕设要求参见标准测试模型，给出接收信号眼图及系统仿真误码率。( Including the least squares method, the SVM, neural networks, 1 _k neighbor method, Undergraduate complete set requirements refer to the standard test models, The received signal is given eye and BER simulation systems.)

说明：  32个脉冲调制的线性调频连续波发射信号，单目标回波信号中加入了距离时延与多普勒频移信息。数字下变频后再进行脉压与MTD处理从而检测出距离与速度信息(For 32 LFMCW signals, the range delay and Doppler shift information are added to the echo signal of single target. After digital down conversion, pulse pressure and MTD are processed to detect the distance and speed information)

电脑编程技巧和源码。很不错的。(computer programming skills and source code. Very good.)

pmsm 位置环 速度环 电流环 采用pi 控制(pmsm position The position loop speed loop current loop adopts PI control)

《PB实用技巧集锦》适合新手,看了此书，pb成长应该会很块(" PB practical skills Collection" for novice, read the book, pb growth should be very block)

说明：  电子战辐射源探测与定位随书光盘,这本书分为三个部分：探测，到达角估计，和地理定位。每一节从介绍相关信号处理理论（检测或估计）开始，然后提供一系列章节，涵盖实现所需最终产品的特定方法。(The book is divided into three parts: detection, angle of arrival estimation, and geolocation. Each section begins with an introductory chapter covering the relevant signal processing theory (either detection or estimation), then provides a series of chapters covering specific methods to achieve the desired end-product.)

说明：  对IQ接收器最重要的两个参数,即I和Q两路分量之间的幅度一致性和相位正交性,可采 用如下办法计算:把I、Q 两路信号分别作FFT ,找出频域内信号的幅度,即可算得两路分量的幅度一 致性 把I、Q两路信号合成一个复数信号,作FFT ,对得到的频谱求镜像抑制比(即频域内的信号与信号镜像的幅度比) ,通过镜像抑制比和幅度一致性,可求出接收机的I和Q两路分量之间的相位正交性。(IQ receiver for the two most important parameters, namely I and Q components of two-way consistency between the amplitude and phase orthogonality may be adopted calculated using the following method: to I, Q 2 signals, respectively for FFT, to find a frequency domain signal amplitude, can be considered as two-way component caused by the range of 1 the I, Q 2 signals into one complex signal for FFT, the spectrum demand of the received image rejection ratio (ie, frequency domain signal and magnitude of the signal mirror ratio), through the image rejection ratio and extent of consistency, the receiver can be derived I and Q phase between the two-way component orthogonality.)
