PSO--PID

this is useful to anty other applications

要求使用继电自整定方法对其实施自适应PID控制。 1、选择采样时间0.1s，把对象离散化。 2、加继电（开关）控制，测量对象的Tc,Kc。 3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。 4、实现闭环控制。 5、根据调节效果，修正PID参数。 (Require the use of relay tuning methods for its implementation of the adaptive PID control. 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)

NOMA的吞吐量的计算，可以正确计算出结果。实测有效。(The throughput of NOMA can be calculated correctly. The measured results are effective.)

利用差值法根据已经给定的多个数据点画图 得到五个图形(Using difference method has been given under a number of data points are five graphic drawing)

说明：  求均方根值,可以用在求图像或者求频谱的时候应用。(solve the square)

离散Meyer小波包变换，主要是Meyer函数构造的相关程序(Meyer discrete wavelet packet transform, mainly related to the program Meyer Constructor)

这是用matlab开发hmm模型，里面包含全部的有关hmm的程序，都可以使用，对于hmm的初学者来说，是极好的的学习程序。(HMM)

说明：  MATLAB实现的FIR滤波器设计系统。可设计LP、HP、BP、BS四种滤波器，窗型和其他参数也可自由设定(MATLAB realization of FIR filter design system. Can be designed LP, HP, BP, BS in four filters, windows and other parameters can also be set free)

这是很多歌窗函数的示例，包含矩形窗、布莱克曼窗等等(chuang hanshu )
