说明：  在对永磁风力发电机的基本理论进行论述的基础上，分析了变转速变桨距控 制策略，并基于Matlab／Simulink建立了风力发电机模型，通过仿真分析了最大功率跟踪 和变桨距控制下发电机的性能。(this paper analyzes variable speed and variable pitch control strategy on the foundation of discussing basic theory of permanent magnet wind turbine generator．Then it builds simulation model of permanent magnet wind turbine generator based on Matlab／simulink and analyzes performance of generator under maximum power tracking and variable pitch contr01．)

一本关于介绍2015年发表的关于扩展有限元的SCI论文的论文集书籍，非常实用(In the standard FEM, cracks are required to follow element edges for the discontinuity modeling. In contrast, the crack geometry in the extended finite element method (XFEM) need not be aligned with the element edges and thus is independent of the background mesh.)

LPC1788官方原理图文件，PCB文件暂时我也没有，不过在设计时这篇文档还是有极大参考(LPC1788 official schematic documents, PCB files temporarily I did not, but in the design of this document or a great reference)

用GAL16V8设计可变长度序列信号发生器，在掌握伪随机序列性质的基础上，设计给定长度的伪随机序列信号发生器，也即设计给定n后（n为移位寄存器的级数）最长线性反馈移位寄存器序列。并在给定n产生的最长序列的基础上，截短出课题给出的序列长度，并用FM软件对可编程器件GAL16V8进行编程，以实现长度不同的序列信号发生器。(GAL16V8 design variable-length sequence signal generator based on the master pseudo-random sequence nature, the design of a given length pseudo-random sequence Signal generator, designed for the series) up to linear feedback shift register sequences given n (n is the shift register. And given n Sequence length given by the subject on the basis of the longest sequence, truncated, and FM software for programming the programmable device GAL16V8, in order to achieve Different length of the sequence signal generator.)

说明：  软件设计报告，包括分数统计软件，打字软件，文本编辑器，打字软件，进制转换器，学生管理系统，模拟电信计费系统，统统都是源码，还有详细的设计报告(Software design report, including scores of statistical software, typing software, text editor, typing software, binary converter, student management system, telecom billing system simulation, all are source, as well as the detailed design report)

说明：  求解二维波动方程，包括论文，公式依据和程序源代码(Solving two-dimensional wave equation, including papers, formulas and procedures based on source code)

改程序是郭磊，基于定向二维插值的逆投影变换方法论文中对应的程序，对于学习该篇论文的朋友有一定的帮助。(Guo Lei reform program is based on inverse projection transform paper orientation corresponding two-dimensional interpolation program for learning the papers friends will certainly help.)

在电网电压频率波动或者三相不平衡的情况下,硬件锁相很难准确检测到基波正序的相位。在结合PWM整流器空间矢量解耦控制算法的基础上,将软件锁相环技术应用在PWM整流器控制系统中,并用仿真和实验验证了该方案的可行性。实验结果表明,该方案解决了电网电压频率波动及三相不平衡时的相位同步等问题,并在工程上具有一定参考价值。(Frequency or voltage fluctuations in three-phase unbalanced case, the hardware lock is difficult to accurately detect the fundamental positive sequence phase. In the space vector PWM rectifier with decoupling control algorithm based on the software used in the PWM rectifier PLL control system, and use simulation and experimental verification of the feasibility. Experimental results show that the solutions to address the voltage and frequency fluctuations of the phase unbalanced three-phase synchronization issues, and the project has a certain reference value.)
