1.设计自适应信号分离器，用以从白噪声中提取周期信号。其中选取正弦信号s=sin(2*pi*t/10)为周期信号，宽带噪声信号为高斯白噪声，设置参考通道延迟为50。 2.宽带信号中的窄带干扰抑制实际上是自适应信号分离的一种应用，借助自适应信号分离器可以方便的实现窄带干扰的对消。(1. Design of adaptive signal separator, used to extract from the white noise periodic signal. The extraction of sinusoidal signals s = sin (2* pi* t/10) for periodic signals, broadband noise signal is Gaussian white noise, set the reference channel delay of 50. 2. Wideband signals in the narrow-band interference suppression is actually an application of adaptive signal separation, using adaptive signal separator can be easily achieved narrowband interference cancellation.)

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.)
