多个关于有源电力滤波器的仿真例子，所有例子都有调试完毕，对学习APF有帮助(A plurality of active power filter on simulation example, all the examples have debugging, learning APF helpful)

利用Matlab编程实现对lena.bmp灰度图象进行QF=50和QF=40的压缩和解压缩，比较二者的PSNR，并且利用霍夫曼编码模拟信道中传输图象。通过了Matlab2009A测试。(Using Matlab program to compress and decompress the gray image Lena.bmp at QF = 50 and QF = 40,as well as comparing the result of two situation.Then using Huffman coding analog channels transmitted images. Adopted Matlab2009A test.)

说明：  卡尔曼滤波源代码，含有噪声设置，特别适合初学者(Kalman filter source code, with noise, especially for beginners)

现代数字信号处理中的卡尔曼滤波的matlab实现，通过迭代逼近真实值。(Kalman filter matlab modern digital signal processing to achieve through the iterative approximation of the true value.)

说明：  倒立摆，Inverted Pendulum ，是典型的多变量、高阶次 ，非线性、强耦合、自然不稳定系统。倒立摆系统的稳定控制是控制理论中的典型问题 ，在倒立摆的控制过程中能有效反映控制理论中的许多关键问题 ，如非线性问题、鲁棒性问题、随动问题、镇定、跟踪问题等。因此倒立摆系统作为控制理论教学与科研中典型的物理模型 ，常被用来检验新的控制理论和算法的正确性及其在实际应用中的有效性。从 20 世纪 60 年代开始 ，各国的专家学者对倒立摆系统进行了不懈的研究和探索。(Inverted pendulum is a typical multivariable, high order, nonlinear, strongly coupled and naturally unstable system. The stability control of inverted pendulum system is a typical problem in control theory. Many key problems in control theory can be effectively reflected in the control process of inverted pendulum, such as nonlinear problem, robustness problem, servo problem, stabilization, tracking problem, etc. As a typical physical model in the teaching and research of control theory, inverted pendulum system is often used to test the correctness of new control theory and algorithm and its effectiveness in practical application. Since the 1960s, experts and scholars from all over the world have made unremitting research and Exploration on the inverted pendulum system.)

极坐标法的潮流计算程序，非常适合各位电力同仁(Polar coordinates of the flow calculation procedure is very suitable for you Power Associates)

TotalWES.m是主干程序，而DCoef和FCTforAW是里面调用的函数。TotalWES只要实现交错网格有限差分波场数值模拟，其中的FCTforAW是用来消除数值频散的。这些是实现弹性波波场模拟的程序，其它两个文件是实现声波波场模拟的程序(TotalWES.m is the backbone of the procedure, and DCoef and FCTforAW is inside a function call. As long as the realization of TotalWES staggered grid finite difference numerical simulation of wave field, which FCTforAW is used to eliminate the numerical dispersion. These are the realization of elastic wave field simulation procedures, the other two documents are to achieve the sound the ball field simulation procedures)
