Hi, I would like to get bode plot from FFT data. How do I convert the data obtained(complex values) so that it can be used by the 'bode' function in matlab. Thanking you. 댓글 수: 0 댓글을 달려면 로그인하십시오. ...
使用MATLAB的Bode命令可以快速画出Bode Plot。不过手绘Bode的能力也是非常有用的,很多时候我们可以快速草绘一个近似图线来做出判断,并不需要借助计算机。单独环节的Bode Plot是十分重要的,这一篇我们主要讲讲几个非常常见的传递函数环节(term)的画法,重点是微分环节和积分环节。 本篇目录: 1. Bode Plot 原理 2. 三...
Another use is for gaining insight into behavior of dynamic systems. For example, the plot clearly shows if the system is stable, how fast it will respond to commands, and if there are one or more frequencies where the system will have a resonance. ...

画bode图有两种方法,我采用的方法是通过模型生成,也就是通过simulink模型搭建传递函数,在通过matlab自带的工具箱生成bode图。 步骤一:搭建模型。根据所需要的系统搭建传函模型,我认为这种方法是最为直接和方便的,每个环节的传递函数一目了然。 步骤二:打开bode图工具箱。运行一下模型,然后打开如下选项卡。并将信号源...
MATLAB Online에서 열기 I use the following data and MATLAB functions to plot the PSD from the input data: xn = rand(3001, 1);% Input signal n = 3001; NFFT = 2^nextpow2(n)+3; Ts = 0.001; Fs = 1/Ts;% Sample Frequency ...
bodeplot(sys1,'r',sys2,'b'); legend('sys1','sys2'); From the plot, observe that both models produce about 70% fit to data. However, sys2 shows higher uncertainty in its frequency response, especially close to the Nyquist frequency. Now, use linspace to create a vector of frequencie...
