有关SIMULINK的教程，在学校时学习MATLAB是同学给的。(Tutorial of SIMULINK)

33节点潮流计算，可以任意断开开关并判断孤岛和环网(33bus power flow calculation)

说明：  模型中明显地体现出模型设计主要有电流调节器和转速调节器两个负反馈闭环组成， 把转速调节器的输出当成电流调节器的输入，在通过电流调节器的输出控制后面的电路。 在这里电流环为内环，电压环为外环，所以形成了转速电流双闭环控制的直流调速系统。(The model obviously shows that the design of the model mainly consists of two negative feedback loops: current regulator and speed regulator, Take the output of the speed regulator as the input of the current regulator, and control the circuit behind it through the output of the current regulator. Here, the current loop is the inner loop and the voltage loop is the outer loop, so a DC speed regulation system with speed current double closed loop control is formed.)

二进制LDPC码的一种构造方法mackey构造，是学习LDPC码的基础(Binary LDPC code construction method mackey construction, is to learn the basis of LDPC codes)

图像检索,MATLAB编译,还可以用用,希望看看(Image retrieval, MATLAB compiler, and can be used with, hope to see)

粒子群算法，可以自己确定惯性系数的函数式，扩展性良好，可以实现多维(Particle Swarm Algorithm)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。(This program is the most basic particle swarm optimization procedures, using Matlab to achieve, is very simple.)

实现主动频率偏移法的孤岛检测，利用matlab中的S-FUN编写(Frequency offset for active islanding detection method, using matlab written in S-FUN)

The work presented in this thesis includes control system design, analysis and grid synchronization of a DFIG (doubly-fed induction generator) driven by a wind turbine using stator-voltage and stator-flux oriented frames. The DFIG is a special type of induction machine which is comprised of two back-to-back converters. One converter connects the DFIG stator to the grid, and the second converter is connected to the rotor of the machine through a DC-link capacitor
