一、绘制波特图并获取句柄 在MATLAB中,可以使用bodeplot函数绘制系统的波特图。通过给bodeplot函数传递系统(通常是一个传递函数或状态空间模型),我们就可以得到一个波特图。为了调整Y轴范围,需要首先获取该波特图的句柄: sys = tf([1], [1, 1]); % 示范用的简单一阶系统传递函数 [h, ~, ~] = bodeplot(...

Bode Plot将系统的频率特性 G(jω) 用图示的方法表示出来。Bode Plot一大优点就是把整个频率特性的作图分解为传递函数的不同零极点和增益的幅频和相频曲线的简单叠加。我们知道一个传递函数中的零极点和增益决定了系统的响应形式,因此通过研究每个零极点和增益的幅相曲线,就可以理解每个环节在整体系统中作用。最后通...
During the process, I came across the following blog (https://in.mathworks.com/matlabcentral/answers/1628890-determine-the-bode-diagram-or-a-transfer-function-with-input-output-data-without-tfest ), where I could able to understand the gain and phase margins + coherence function plot ...
I wrote thisplot(app.UIAxes,bode(TF)); and works for step response and for rlocus but when I try to plot bode function it gives me this error:Error using plot, Data cannot have more than 2 dimensions. I want to show the bode plot in the UIFigure not in other window. ...

When you invoke this function without left-side arguments, bode produces a Bode plot on the screen. The magn itude is plotted in decibels (dB), and the phase in degrees. The decibel calculati on for mag is computed as 20log 10 (|H(j 3)|), where | H(j w)| is the systems ...
