无传感器永磁同步电机仿真，基于滑膜变结构控制(Sensorless permanent magnet synchronous motor simulation, based on variable structure sliding mode control)

Module Provides implementation of SURF Points to detect invariant features input image for robust image matching. It takes less time to detect features an image rather than SIFT

信号去噪的基本步骤： （1）信号的小波分解； （2）小波分解高频系数的阈值量化； （3）信号的小波重构。使用分解的低频系数以及阈值量化后的高频系数进行小波重构。 (The basic steps of signal denoising:( 1) of the wavelet decomposition of signals ( 2) the high frequency coefficients of wavelet decomposition threshold quantization ( 3) the signal wavelet reconstruction. Using the decomposition of the low frequency coefficient and threshold quantization the high-frequency coefficient after wavelet reconstruction.)

小波变换实现信号的去除噪声，仿真效果良好(Wavelet transform to remove the noise signal, the simulation results good)
