9:45 - Defining transfer functions
15:00 - Laplace transform of a derivative
27:32 - Example of transfer function with mass, spring, damper

My goodness this is an absolutely incredible video, its only an hour long but it takes you through every potential experience you can have with transfer functions even extending it to simulink and matlab which was fantastic. I also am an aerospace engineer and so I was very happy and at home so to say with your initial plane system model. You are a very smart man things clicked smoothly and quickly for me, its like you were born to be a teacher. Excellent work, you've more than deserved a new subscriber and an additional like to your videos. Fantastic work keep it up!

The demonstrations at the end were so helpful and inspiring. Thanks for your effort.
Easy to follow breakdown of TF, the mathematica use in the end was very helpful. thank you.
Once again I praise your videos and this time I'm pointing out how useful is for us student that you actually contextualize concepts explaining how they interconnect and how to apply them in practical scenarios. This is rare to find in this kind of youtube lectures (oftentimes the real final goal of a mathematical procedure is not even mentioned...)
I'm watching your videos to prepare for a master of science in acoustic engineering and they're really helpful.
also, ahahah... while you were plotting on Mathematica I continuously paused the video to figure out how to get the same thing on Matlab aaaand then you showed us, ahah should have predicted that
Hiyori, that is great to hear you're getting into acoustic engineering. This is a fascinating realm I haven't had much exposure to but as you've discovered, control theory spans multiple disciplines. I hope to hear from you at another video!
AE511: Good intro to transfer functions. I had heard of this before and possibly even had a light intro in my bachelors program but never understood what they were. This was helpful.
You are a blessing to the world. Thank you sir!

It's been a decade since I took college calculus, so I had to replay this video a few times. I think I understand conceptually, but I definitely need more instruction of fundamentals.
There are other videos on the channel that may be helpful. Thanks for watching!
Awesome lecture series. Thanks a lot for dedicating your time to teach us :-)
When the lecture started off it was assumed that there are N inputs (of y) and M outputs (of u). But when writing the general form of the LTI, where [output equation] = [input equation] the n and m were switched. No problem, it was consistent within that discussion.
Small note: I used "lsim" function instead of using Simulink (of Matlab), and the good news is open source software Octave has "tf" and "lsim" functions. Just remember to load package named "control" to get the TF features. I used "gensig" function to generate the input.
Thanks once again for the series.
I'm glad it was helpful and thanks for the thoughtful discussion. I hope to catch you at another video. Thanks for watching!
Hey Christopher, I don't know how to thank you, brilliant pedagogy!!!
Esse é o canal do controle! Penas que achei somente no fim da faculdade. Mas ainda da para aproveitar para o TCC.
Abaixo assinado para todas as faculdades que tem a matéria na grade ter como referência esse canal ! kkkkk
AE 511: Software examples are especially helpful, thanks.
This is very understandable video i have ever seen, thank you for renewing my interest to the control theory.

Once again, hats off to the Teacher (yes, capital T). Thanks.

Most of the time, I need to watch the lectures on YT 2-3 times before I totally understand the subject. But, It only took one time to absorb this. Thank you so much for such an extensive playlist of control engineering. Do you have a lecture video on z transform for signal sampling? I tried looking for it but couldn't find anything.

Excellent review of TF's and using them Matlab, Mathematica and Simulink!
thank you so much sir
Very helpful, thank you.

Great summary of transfer functions
How did you get your start in control theory just wondering?
thank you very much，appreciate your effort.very very very useful material!
AE511, Thank you for all these videos
Good intro to transfer functions.
YOU are the best

AE511-Great Intro to TF.
thank you for all effort
wonderful lecture. One moe thing, could you please make some vedios about control system identification?
very useful sir, thank you
And thus legend was born
I'm glad it was helpful, thanks for watching!

can you tell me the lecture which you are referring for laplace transform?
Hi, your teaching is fantastic. Haw can I have access to high quality of your videos? Thanks
Thanks a lot :)

There is a theory among the model plane makers is this that, we have to give a slight pitch down to the motor and prop combo for stability for a tractor type and a pitch up for pusher type. what exactly is the physics behind that theory.
AE 511. Great video.
Great. I like the explanation.
Do you use the book "fundamentals of modern control by Ogata"?
i want to know too
Hi, I notived that your formula for the Laplace transform of the nth derivstive should be s^nF(s)-s^(n-1)f(0)-s^(n-2)f'(0)-...-s^0f(n-1)(0)
Thanks a lot 🙏

Can i show e^-5s like that etc in simulink particularly using LTI or TF block ...? Any other block for suggestions?
Hi sir, kindly make a video on Nyquist stability criterion.
Does the non linear systems are MIMO?
professor can i ask which book you are following ?
ı appreciate for this usefull videos

thankyou for your video then how about the linear quadratic tracking? linear quadratic gaussian

AE511, good lecture
Good
can you tell us any books?
On previous comment nevermind. I didn't see your lower case ns in the equation on my tiny screen.
What do we do in the case of a non-zero initial condition? For example, the differential equation y''(t)+y'(t)+y(t)+C = u(t). Is it possible to write a transfer function for this system? Is there a way to use substitutions with a change of variable (not sure how though)?

Hi professor, your video on control theory hasn't been updated for a long time!Expect to see more of your videos on control theory, especially the linear estimator you mentioned in the previous video.Your video helped me a lot. Thank you for your video. I wish you good health and all the best
Hello Mr Christopher lum I'm an aeronautical engineer . I'm following your TH-cam channel to learn control theory. Can you suggest any book for referring on aircraft control theory?
Thank you very much
