一个自适应pid，用matlab来实现，可以在此基础上进行修改成自己的可用程序(An adaptive pid, using matlab to realize, on this basis can be modified into its own procedures available)

Interconnect line capacitance and coupling effect

产生64QAM基带通信系统发射机：基带成型滤波采用3种方式（1）采用每个符号调制一个成型滤波函数，然后将各个函数进行时域叠加的方法； （2）采用信号与低通滤波器响应函数卷积的方法；（3） matlab自带的升余弦函数(Produce 64QAM baseband communication system transmitter: baseband shaping filter uses three ways (1) the use of a molding each symbol modulation filter function, and then each time domain overlay function (2) the use of signals and low-pass filter response function convolution method (3) matlab comes with a raised cosine function)

this code can be used to compute classic harmonic analysis

电能质量扰动信号信号通过hilbert变换得到瞬时频率，瞬时幅值，hilbert谱，边际谱等重要特征，从而实现特征提取。(Power quality disturbance signals are obtained by hilbert transform to obtain instantaneous frequency, instantaneous amplitude, hilbert spectrum, marginal spectrum and other important features, in order to achieve feature extraction.)
