用于计算椭圆的正交点用于椭圆几何参数的拟合(Quadrature points used to calculate the ellipse fitting for the elliptical geometry)

做过模糊PID的朋友很多遇到过这种问题，就是仿真启动不起来，停留在e-7等地方或者仿真很慢，自次上次有个朋友说改变步长能解决这个问题，最后的曲线能达到满足要求的时候，我让他找个例子他就没有后文，以前我做了很多这样的模糊PID，但靠改变步长并没有解决问题，仿真曲线直接发散出去了，我自己这两天也总在思考这个问题，通过不断的调试总结，明白了不少，给遇到这个问题的朋友讲解一下解决办法吧，以一个例子详解：(Done a lot of friends of the fuzzy PID encountered this problem, simulation start up, stay in the e-7 and other local or simulation is very slow, have a friend who said to change the step size to solve this problem since the times the last, the finalcurve to achieve to meet the requirements when I asked him to find examples of his later, I have done a lot of fuzzy PID, but by changing the step does not solve the problem, the simulation curve directly divergence out, Itwo days always thinking about this problem, summarized by the debug and understand a lot of friends to experience this problem to explain the solution, an example Detailed:)

FIR滤波器的设计代码，这是其中的一部分，剩下的陆陆续续会传到这里(FIR filter design code, which is a part of it, the rest will continually spreads)

已经调试好的SVPWM模型，搭建了逆变电路，效果还不错(SVPWM model has been debugged, set up the inverter circuit, the results were good)

时频分析方法文章，对时频分析方法进行了解析，具有一定的参考价值。(Time-frequency analysis method articles, resolution, time-frequency analysis method has certain reference value.)

用于求信号的自相光与互相关 (compute autocorrleation and cross-correlation)

多用户检测的三种子空间方法的仿真对比的是误码率-信噪比性能(Third seed space simulation comparison of multiuser detection method is BER- SNR performance)

ABAQUS uhard子程序的相关资料介绍，可以用来学习ABAQUS(Uhard ABAQUS subroutine of the relevant information, can be used to learn ABAQUS)

说明：  采用人工智能神经网络的改进Holpfield神经网络解决旅行商问题(Improved use of artificial neural network neural network to solve the traveling salesman problem Holpfield)

A good Appendix from Wiley Pub Group for understanding Genetic Algorithm you can download from Wiley Web.
