EKF_PF 基于扩展kalman的粒子滤波 可解决非线性状态估计问题(EKF_PF based on extended kalman particle filter to address the issue of non-linear state estimation)

Pattern formation and KPP equation

说明：  根据经典光学光折射理论，模拟光在界面上的折射，(According to the classical theory of optical light refraction to simulate the refraction of light at the interface,)

雷达高斯分布相干视频噪声和高斯分布中频噪声仿真(Coherent Radar Gaussian noise and Gaussian frequency video noise simulation)

《小波分析理论与MATALB R2007 实现》里部分章节的matlab源程序，很有用(wavelet analysis using matlab.)

利用MATLAB实现屏蔽电缆转移阻抗解析计算的典型方法之一——Tyni模型。已调试成功(Use of MATLAB shield cable transfer impedance analysis-one of the typical method of Tyni model. Already debugging success)

说明：  用DE遗传算法整定最优PID控制器，得到控制器最优的三个参数(The optimal PID controller is set by DE genetic algorithm, and the optimal three parameters of the controller are obtained.)

里面有三个二维模糊调节器分别实现PID控制器的参数Kp，ki，Kd，的调节。其控制原理：根据前面的偏差e和偏差变化ec将三个模糊控制器FC1,FC2,FC3分别进行模糊化，模糊逻辑推理，解模糊化。最后得到pid控制器参数调节量。(There are three-dimensional fuzzy regulator PID controller parameters Kp, ki Kd, adjust. The control principle: the front of the deviation e and error change ec three fuzzy controllers FC1 has FC2, FC3, fuzzification, fuzzy logic inference, defuzzification. Finally, get the pid controller parameter adjustment.)
