This project consists of two back to back pwm converters used for simulation of traction load in normal operating mode. The first side is connected to a single phase network and uses hysteresis current control. The second side is connected to a three phase network and uses space vector modulation for controlling its inverter.

用MATLAB编写与仿真了MSK信号，其中结合了自己写的快速傅立叶变换实现了MSK信号的调制还有解调，而且作为拓展，还加入噪声、通过带通滤波器、低通滤波器、载波信号等等。调制解调都很有用，画出的图也很漂亮规范。(Using MATLAB and the simulation of the MSK signal, which combines the fast Fourier transform to write their own modulation there demodulation of MSK signals, but also as a development, but also by adding noise, band-pass filter, low pass filter, the carrier signaland so on. The modem is very useful to draw the plan is also very beautiful and specification.)

关于matlab计算的代码，主要为拉曼激光器输出与输入的关系，希望大家下载啊(Calculated on the matlab code, mainly for the relationship between the Raman laser output and input, I hope you download ah！)

正确率可以达到98％，仿真图是速度、距离、幅度三维图像，这是第二能量熵的matlab代码。( Accuracy can reach 98 , FIG simulation speed, distance, amplitude three-dimensional image, This is the second energy entropy matlab code.)

人脸识别作为一个复杂的模式识别问题，近年来得到了广泛的关注，识别领域的各种方法在这里各显所长，而且发展出了许多新方法，大大丰富和拓宽了模式识别的方向。现有一个描述人脸不同角度的图像库，包含了10个人，每人5幅图像，分别描述人脸的朝向：左方、左前方、前方、右前方和右方。创建LVQ神经网络，对任意给出的人脸图像进行朝向预测和识别。 相比与BP神经网络，LVQ神经网络无需对数据进行预处理，只需要直接计算输入向量与竞争曾之间的距离，从而进行模式识别。近年来，对LVQ神经网络的研究也愈来愈深入，应用也越来越广泛，如故障诊断、性能评价、风险预测等。
