在输入输出信号中加入高斯白噪声。这是在很多工程领域必须加入的。此文件是matlab中信号加入高斯白噪声的文件(In the input and output signals in white Gaussian noise. This is in many engineering fields must be added. This file is in matlab adding Gaussian white noise signal file)

用MATLAB程序软件完成Z-N法对控制器的参数整定，实现P,PI,PID控制器的分别参数整定，并求出控制器的控制参数Kp，Ti，Td。最后绘制出不同控制器控制下的及参数整定前后的单位阶跃响应图进行比较。(MATLAB program software is used to complete the parameter tuning of the controller by Z-N method. The parameters of P, PI, PID controller are adjusted, and the control parameters of the controller Kp, Ti, Td are obtained. Finally, the unit step response diagram before and after parameter tuning is plotted under different controller control.)

该函数用来计算任意函数的一阶偏导数(数值方法),毕业设计有用，具有丰富的参数选项。( This function is used to calculate the arbitrary function of the first order partial derivative (numerical methods), Graduation useful It has a wealth of parameter options.)
