卡尔曼滤波仿真算法！！！经典的哦！！！！！！！！(Kalman filter simulation algorithm. ! !)

PID模糊控制，matlab 运行仿真，实现模糊控制的PID参数优化(PID fuzzy control, Matlab run the simulation, PID parameter optimization of fuzzy control)

its of signal and system in matlab.

说明：  对一个二阶模型模型进行脉冲响应辨识，并且通过搭建simulink模型取得了两组输入-输出数据，一组是在有高斯噪声的干扰下获得u1-y3，另外一组是在没有高斯噪声的情况下获得的u1-y1，对这两组数据进行基于haar小波基的脉冲响应辨识，与实际模型的脉冲响应相比较（注：三个excel表必须放在matlab/work文件夹下才能运行）(Second-order model to a model of impulse response identification, and achieved through building simulink model for two groups of input- output data, a Gaussian noise in the interference with access to u1-y3, another group in the absence of Gaussian noise of access to the u1-y1, these two sets of data haar Wavelet-based impulse response identification, and the actual model of the impulse response comparison (Note: Three excel table must be on the matlab/work folder to run ))

基于saleh模型的记忆放大器仿真程序，用做预失真均衡项目可以用的前置记忆功率放大器的非线性失真模型。(simulation for memory prodistorition )

SOM神经网络，可以进行特征提取和模式分类，特别是特征维数较多的情况(SOM neural network, feature extraction and pattern can be classified, more especially characteristic dimension of the case )

该程序不使用matlab自带的程序，自主编写，进行简单更改可以实现多中功能，算法思想是滤波器的实现！(The program does not use matlab own procedures, self-writing, more than a simple change in function can be achieved, the algorithm idea is the realization of filters!)

单级机械臂的位置控制，由于需要调整时间和最大输入力矩的要求，程序实现两种非标准的LQR控制(The single-stage manipulator position control, due to the need to adjust the time and the maximum input torque requirements of the program to achieve the two non-standard LQR control)

图像直方图的绘制，此程序提供两种方法，一是利用matlab自带得工具箱绘制，另一种是利用统计学的方法编程实现，最后对两种方法进行比较(Image histogram drawing, this program provides two methods, one using matlab toolbox comes too draw, another is the use of statistical methods to program implementation, and finally to compare the two methods)

绘分形树：tree(n,a,b),n为分形树迭代次数 a,b为分枝与竖直方向夹角 (Painted fractal tree)
