对单级倒立摆系统的平衡控制问题进行了研究.。首先建立了系统的数学模型 ,然后采用 PID 方法设计控制器 ,最后对控制系统进行了仿真实验研究. 仿真实验结果不仅证明了PID方案对系统平衡控制的有效性，同时也展示了它们的控制品质和特性.。(The balance control of a single inverted pendulum system was focused. First , the mathematical model of the system was built , then the PID method was adopted respectively to design the controllers, at last , the simulation experiments were finished, by the simulation experiment results, not only the validity of the three methods were confirmed , but their qualities and characteristics were shown fully also.)

通过学习LDPC编译码原理，编写了LDPC码的编译码程序。通过此程序可以更好的实现LDPC码的仿真(in this passage we have write the program of edcoded and decoded of LDPC code.through it we can undersatand LDPC more.)

说明：  一个非常优秀的人脸检测matlab程序，可用于人脸跟踪、识别的基础，附有测试图片！(A very excellent face detection matlab program can be used to face tracking, recognition based on testing with pictures!)

1、 从网上下载人脸图像，构建人脸训练数据库和测试数据库，采用K-L变换进行特征脸提取，并实现人脸识别。通过K-L变换在人脸识别中的应用，加深对所学内容的理解和感性认识。(1, face image downloaded from the Internet, the construction of the training and test database face database, using K-L transform features face extraction, and realize the face recognition. Through k-l transform in face recognition application, deepen the understanding of the content of study and perceptual knowledge.)

用汇编语言编写卷积运算。Visual DSP++软件环境下使用三角波和正弦波卷积运算验证程序，与MATLAB仿真结果对比。 (Convolution written in assembly language. Visual DSP++ using the triangle wave and sine convolution validator software environment, compared with the MATLAB simulation results.)

说明：  共轭梯度酸的具体介绍，非常有的东西，希望大家可以学的到这些(Acid conjugate gradient specific description, is there something I hope we can learn these)
