双线性变换法设计Butterworth滤波器。分别画出滤波前和滤波后的时域图和频谱图。(Bilinear transform design Butterworth filter. Draw the pre-filter and the filtered time-domain and frequency spectrum.)

基于 M atlab/Simulink 环境，分别建立小水电、双馈感应风力发电和超级电容 储能系统的模块化仿真模型，(micro grid)

频率切片小波变换程序（FTWT），matlab的m文件。从一种新的角度出发，通过自由选择频率切片函数、引进新尺度参数，在频率域实现小波变换，该变换能够很好地刻画信号各成分之间的相对能量关系。此外，频率切片小波变换的时频窗中心频率就是观测频率，而无需进行尺度换算。(Frequency slice wavelet transform procedures (FTWT), matlab m file. Starting from a new angle, through freely chosen frequency slice function, the introduction of a new scale parameter, the wavelet transform in the frequency domain, the transformation can portray the relative energy relations between the components of the signal. In addition, the frequency slice wavelet transform frequency is the observation of the time-frequency window center frequency without scale translation.)

一篇博士论文，关于降低OFDM峰均比的，提出了新方法，是关于矩阵变换降低OFDM峰均比(A doctoral thesis, on reducing the PAPR of OFDM, this paper puts forward a new method of matrix transformation, is to reduce the PAPR of OFDM )

1.why there is a spike at every peak of current wave form? how to eliminate this? 2.actual current before filtering is around 6 amps peak , but after filtering it is giving 8.5 amps ,even after changing KP,KI values in PI controller reference value is not coming down...
