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.)

说明：  提供了通信系统仿真链路的基本知识,对通信系统仿真初学者很有用。(show the base knowledge on the simulation of communiaction link.)

Shows single- and two-stage-decomposition of a sample image, as well as reconstructed branches. The reconstruction error is shown. Also demonstrates that better compression can often be obtained if different thresholds are allowed for different subbands.

函数作用： cwstd.m——用综合标准化法标准化矩阵 Cwfac.m——计算相关系数矩阵，计算特征向量和特征值，对主成分进行排序，计算各个特征值的贡献率，挑选主成分（贡献率达与85 ），输出主成分个数，计算主成分载荷 Cwscore.m——计算各主成分得分，综合得分并排序 Cwprint.m——读入数据文件，调用以上三个函数，并输出结果 原始数据：存储在src.txt中是一个30×8的矩阵 敲入命令： (PCA)
