Draw a bode and nyquist diagrams

[gimini75]

I have a task to draw a bode and nyquist diagrams from an expirmential results by using MATLAB, I have the phase delay and the votage gain data (10 results for each), can you help me how to darw bode and nyquist diagrams in MATLAB and which command I can use?



thanks

I think you only need to use "semilogx" plot for drawing the bode plot. To draw the nyquist plot you could use the magnitude and phase to get the complex coordinates, then plot them as usual using "plot".

for your question. I understand the importance of visual aids, such as bode and nyquist diagrams, in representing experimental data. I would be happy to assist you in drawing these diagrams using MATLAB.

To draw a bode diagram in MATLAB, you can use the "bode" command. This command takes in the frequency vector and gain vector as inputs and plots the magnitude and phase response of the system on a logarithmic scale. You can also use the "semilogx" and "semilogy" commands to plot the magnitude and phase response separately.

For the nyquist diagram, you can use the "nyquist" command in MATLAB. This command also takes in the frequency vector and gain vector as inputs and plots the complex frequency response of the system on a polar plot. You can also use the "polar" command to plot the magnitude and phase response separately.

It is important to ensure that your data is properly formatted and organized before using these commands. Additionally, you may need to adjust the axes and labels to make the diagrams more visually appealing and understandable.

I hope this helps you in drawing your bode and nyquist diagrams. If you have any further questions, please do not hesitate to ask. Best of luck with your experiment!
