Control System Lectures - Bode Plots, Introduction

This lecture is an introduction to frequency response methods, and in particular describes the Bode plot. I go through how it is generated and why we use it to visualize the frequency response of a system across the entire frequency spectrum.

Errata:
8:31 - I should not have combined both time domain and s-domain in a single equation.
9:31 - it should be 2 - j*1/omega, I correct it at 9:55 but don't let it confuse you!

I will be loading a new video each week and welcome suggestions for new topics. Please leave a comment or question below and I will do my best to address it. Thanks for watching!

This is the best playlist out there for understanding bode plots. Believe me, I am an Electrical Engineer and have studied bode plots a number of times but never had such an understanding.

This is amazing! My signals professor doesn't teach very well and now that we've switched to remote learning, he doesn't give us any lectures and only gives us written handouts that are sometimes hard to understand. I love how succinct yet in depth your videos are! You have no clue how much this helps

You may be the best in the world at explaining these concepts. At least for my style of learning.

Hello Samay, You are absolutely correct. I should have written the equation in the S-domain completely, or Y(s)=2U(s)+U(s)/s. However, I accidentally left the input and output in the time domain. Thanks for pointing this out. I hope this doesn't confuse anyone watching the video.

I paused the video around 9:40 then spent 10 minutes trying to figure out how to get 2+(1/w)j when i kept getting 2-(1/w)j. in the end i gave up and decided to watch the rest of the video anyway only to find you corrected it as a mistake 10 seconds later at 9:50 -_-...

That said, your style of videos are absolutely brilliant!!!... so ill let you off this one time =]

Cheers!!!

Since 2012 (10 Years) this is the best Video about Bode Plots

The things I learned in these video are way more valuable than the ones I learned over two semesters of control courses. This guy tells you every thing why they are there and where they came from and so on. I wish if I had him as a control professor

[BrianBDouglas]

Absolutely! I'm finishing with Bode this week and then want to provide a good practical understanding of stability. I'll touch on root locus at the end of the stability portion and as we get into tuning controllers.

"Your explanation of control systems is amazing. You absolutely nailed it, my friend."

[TY-unno]

I replayed the section explaining the history of decibel unit many times because I was easily distracted by your skilled drawings haha. Thank you for creating clear and fun educational videos!

[johnsalvadoresabio]

The quality of your videos speak to how much time and effort you put into your channel. Thank you so much. <3

[patriceamyot]

your explanation of the history of decibels is amazing and thorough! Very impressed!

[ahxishwe]

Just realized i had subscribed 10 years back. And i still need to watch your video today. ❤

[Poiarn]

I've never seen or read anything that comes even remotely close to how good this video explains bode plots!
Really good job!!

[HassanOmariprofile]

I have to say this, you are the greatest control teacher I have ever seen

[muratmillidere]

Brian, you are just perfect. Everyone who is interested in control system should watch these videos.

[jacobhardy]

Taught me what my vibrations/control professor couldn’t in a whole semester. Thank you

[eugenenazarenko]

This was an amazing video. I was shocked to see it is over 10 years old at this point, unreal quality!

[naut_nigel]

I can't believe it took me 2 years after graduating when I'm at a professional job to find these hidden gems of videos! Thank you!!

[dylanschink]

These lectures are so helpful, I wouldn't be passing with control theory module without them.
