这个模型解释了DFIG WT的工作。 转子侧变流器模型化为受控电压源，忽略电网侧变流器，因为机器基本上由转子侧变流器控制，大部分有功和无功功率由机器提供。 矢量控制技术用于控制DFIG。 这不是一个完整的模型，而只是那些想了解双馈电机控制的人的起点指南。 机器的有功和无功功率由转子侧转换器调节。(this model explains the working of the DFIG WT. The rotor side converter is modelled as controlled voltage source and grid side converter is neglected as machine is basically controlled by the rotor side converter and most of the active and reactive power is supplied by the machine. The vector control technique is used for controlling the DFIG. This is not a full model but only a starting guide for those who want to learn about DFIG control. the active and reactive power of the machine are regulated by the rotor side converter.)

说明：  仿真轴承故障的振动信号，显示时域波形和频域波形。(Vibration signals of bearing faults are simulated and time domain waveforms and frequency domain waveforms are displayed.)

加速度计数据采集程序 可用于单轴加计的快速数据采集与标定，在MATLAB中迅速编程标定(the programme to get the datas from acceleration)

用fdkmod函数画出采用4-FSK调制的0:3的调制信号波形，以及调制信号的频谱图(4-FSK modulation with fdkmod function draw 0:3 modulated signal waveform, and a modulation signal spectrum FIG.)

<通信系统仿真原理与无线应用>中文版电子书，超星格式的，全书采用matlab仿真，很经典的教材。(<Communication System Simulation Principle and wireless applications> Chinese version of e-books, Chaoxing format, the book using matlab simulation, it is classic material.)
