simulink PMSM-SVPWM

代码实现了超宽带基本定位算法，包括TOA,TDOA,以及TOA三维定位，所有代码已经在matlab 7.1下调试通过(The code is about basic positioning alogrithm of UWB,including TOA,TDOA and the 3d positioning of TOA,all of them is debuged successfully on matlab 7.10.)

this program will make skew correction of character

it is an example for matlab in electrical applications

说明：  利用SVD进行信号降噪，通过fft判断奇异值个数，确定重构矩阵结构(Using SVD to reduce the noise of signal, using FFT to determine the number of singular values, and determining the structure of reconstruction matrix)

基于chebyshev的水声信号分析，多抽样率信号处理，做视觉测量的上位机代码,最小二乘回归分析算法，一个计算声子晶体结构的一维传递矩阵法,已调制信号计算其普相关密度。

根据灰色预测理论，用程序实现预测，效果较好(According to the gray prediction theory, use the program predicts better)

本文件实现空间电压矢量在永磁同步电机直接转矩控制下的电机调速。经过调试可以正常运行。(SVPWM PMSM DTC)

说明：  基于BP神经网络的数据分类-语音特征信号分类(Data Classification Based on BP Neural Network-Voice Feature Signal Classification)
