Introduction to Bode Plots

In this video we introduce the concept of Bode plots including what they represent, how they are generated, as well as how to use Matlab tools to work with Bode plots.

Topics and time stamps:
1:19 – Introduction
5:29 – Defining a Bode plot
8:42 – Demonstration with a real mass, spring, damper system
20:58 – Definition of decibels
30:31 – Workflow to generate a Bode plot
32:34 – Manually creating a Bode plot in Matlab
39:04 – Using Matlab’s ‘bode’ command

AE 511: The lunchbox demonstration is something I'm gonna have to take inspiration. Probably the best bode plot explanation I've seen. Nice job

AE511: At around 15:00 the demonstration with the oscillating backpack absolutely killed it. This is the method of learning that works best for me. I have no doubt I will remember this demo for many years to come.

AE511: The backpack example is perfect, very intuitive! Thanks!

[melissawells]

Thanks for walking through the manual generation of the bode plot and not jumping straight to using Matlab for its generation. It helps with the comprehension

[KcKishan]

Where is the video stated by you on "Frequency Domain Analysis: Introduction and Theory"?

AE511: The example with the backpack + bungee cords and linking the physical response to the bode plot gave me my clearest understanding yet of bode plots. An example always does wonders!

[zaspanyflegmatyk]

That real life example was great! 10/10 I had some hard time understanding what Bode plots are. Thank you :D

Visualization of the Bode plot with the frozen backpack was key. Let it go! Let it

[lorenzomercuri]

Thanks for the video! I finally understand the point of using bode plots.

[ThomasNiemisto]

AE 511: Demos are always helpful, even if a little flawed :)

[thomasfahd]

Thanks a lot for these amazing videos and phenomenal explanations. Would it be possible to post the Frequency Domain Analysis video you mentioned at the beginning? That would be really appreciated.

[brianambelis]

wow this was a phenomenal explanation. i finally completely understand bode plots. thank you so much for making this lecture video

[nitinsiva]

you are so good in conveying concepts..

[gaeguldaegul]

Thanks for sharing this lecture. The demo finally got me understanding Bode Plots!!

[mulelos]

i'm kindda in controls for 4 years tuning servo systems and analyzing bode plots, trying to push the unstable points as far right as possible. But I could never understand what i'm doing in layman terms. Thanks for the video, it has open my eyes and understood more.

[rubensromani]

This video is fantastic. Thank you professor.

[cerensuleozdemir]

such an awesome lecture :) thank you so much from Turkey

[saada]

You're doing wonderful work sir... please keep it up🙌🏻

[selamhendrix]

very helpful to create it manually and compare.

[andrewmelean]

Thank you. If your loop gain has an actuator block, should you combine with the plant block to plot the bode?
