Hi Brian, I cannot emphasize enough , how thankful I (and for that matter other hundreds of people) am (are) for your videos. Looking forward to the continuation of this series. Best to you!
Your videos are incredible Brian! I very much enjoy them all. You are among a few people I've ever seen that has such a deep understanding about the underlying principles of control. Thanks a lot and keep up the excellent job!
Brian, I cant begin to think how I would be doing in my controls systems classes without your content! keep up the great work. You really do make every concept of control systems less daunting for me and my classmates!
Heey..I think I got the chance this time to thank you since the video is just uploaded yesterday, you saved my first semester with your classic control playlist :-) YOU ARE AWESOME REALLY, and I hope you can ends the discrete one soon cause I have a digital control course this semester: 'D and thank you again you cleared a thousands of concepts in both control and signals to me, best of luck
Brian, you are an amazing teacher & a fantastic artist! I really appreciate you putting the time into making these videos. Control theory is so difficult for me to wrap my head around, but somehow you make it so easy to understand.
They never really explained prewarping at my university. They did developed their own tool which automatically warps each filter component at the corresponding frequency, so I always took that for granted. But it is nice to know what is actually going on. PS: that tool also shows you the modulus margin of you plant with designed controller, but from searching online it seems that hardly any other university uses that margin as well.
w-transform is another name that is used for the bilinear transform. w-plane also looks like the s-plane . But I guess your warping method provides a more intuitive understanding on how the poles are really moving due to warp.
Hey Brian, great video as usual! Out of curiosity, what's your occupation? Most likely a controls engineer, but can you enlighten us with details about the specific industry or products you work on?
To convert a continuous domain TF to discrete domain - What are disadvantages of sampling H(s) at discrete frequencies and using invfreqz in Matlab rather than using bilinear transform?
Are you continuing these videos? And do you know of any other good resources for discrete control specifically dealing with state space methods? Thank you!
I am now confused when you took T=2 and said sampled frequency=1/2 and Nyquist Freq =1/4. I studied that Nyquist Freq is 2fmax so it should be 1 i.e 2π rad
Hello Brian, I 've been checking with a low-pass filter of Butterworth and it does not result the same than what you show here. What I did was changing the W at 1%, 50% and 75% and there was no effect. Can you help me. Maybe can I send you my code of Matlab?
Awesome video man ! btw, did you hear about the rumors of state space ? they said that a guy called brain will make it in the next video !! :D :D :P @Brian Douglas
You have been kind of a mentor to me when it comes to controls. Thank you for all the time you invested here... Greetings from Brazil
Thanks Matheus! (Only took a year for me to respond, sorry!)
@@BrianBDouglas
I have a request for you
Do you have any email adresse please?
Thkx
First!
hhh
Take a bow man!
What I could not understand in 4 months, this guy explained in 25 minutes. Kudos!!
Hi Brian, I cannot emphasize enough , how thankful I (and for that matter other hundreds of people) am (are) for your videos. Looking forward to the continuation of this series. Best to you!
Good job man!!! A massive thanks from Greece, Thessaloniki from all the students who are supposed to become engineers
This is one of the most interesting and informative tutorials I've ever seen. 25mins went like 1 min and I understood everything!!
the way you explain everything through your drawing is great
Your videos are incredible Brian! I very much enjoy them all. You are among a few people I've ever seen that has such a deep understanding about the underlying principles of control. Thanks a lot and keep up the excellent job!
These lectures are great for gettin the bigger picture. I often feel lost when solving CT-Problems and your explanations keep me going.
Brian, I cant begin to think how I would be doing in my controls systems classes without your content! keep up the great work. You really do make every concept of control systems less daunting for me and my classmates!
I am doing BE and I must say that you are a life saver. Thank you so much
Thanks very much for help me to understand this complex items. These seems very easy now. Greetings from Perú¡¡¡
that animation was amazing !
Very nice and useful work. Greetings from Brazil
huge thanks from philippines

So many thanks to you!!!! it is so clear lecture! dame useful !!! as a EE student i am very happy to listening ur lecture!
Brian, you are an amazing teacher & a fantastic artist! I really appreciate you putting the time into making these videos. Control theory is so difficult for me to wrap my head around, but somehow you make it so easy to understand.
*click* NOICE
Keep producing content! A huge thanks from Brazil!
Clear explanation! Wonderful Examples!

thank you very much for the videos, are very clear and useful to understand the concepts.
a great contribution!
Thank you Brian. The videos are really great!
the real MVP here
OMG thnks for the all videos. i hope it can make me more understand about this
keep producing content like this sir!!
Your videos are awesome! Keep up the good work.
nice way of teaching ....thanks for the visual realization .
Thank you for all your awesome videos. Looking forward to watching Non-linear control (Lyapunov theory etc), Modern Control Theory.
I love your videos!
Awesome video. one of the most intuitive explanations I've seen on the topic. What did you use to create the warp animation?
Thanks! I used JavaScript and you can download the code at my GitHub: github.com/aerojunkie/control-tools
Excellent video. It would be great if you could make a few videos on other forms of control as well!
i need another video for the next this is awesome
Incredible

Thank you so much your video, it's so cool!
We miss you brian
awesome job!!
To convert a continuous domain TF to discrete domain - What are disadvantages of sampling H(s) at discrete frequencies and using invfreqz in Matlab rather than using bilinear transform?
Aren't we lucky or what?!
Hi spectacular videos. A question: what if I design the filter in time or s domain and then digitalize it using backward euler integration method?
Great!!!!
Sir, Please make videos on State space analysis and design of control systems.
Are you continuing these videos? And do you know of any other good resources for discrete control specifically dealing with state space methods? Thank you!
Awesome video! How did you make those interactive animations on an HTML webpage?
How would you do the discretization in state space model for a MIMO system.
I am now confused when you took T=2 and said sampled frequency=1/2 and Nyquist Freq =1/4. I studied that Nyquist Freq is 2fmax so it should be 1 i.e 2π rad
If Bilinear transform results in warping, why cant we directly substitute, s=1/T*ln(z) ? What benefit does bilinear transform have over this?
sweet!

hey! brian, can u make videos for QFT design or suggest a good referance for that!!
thanks :)
How does bilinear warping affect points outside the z-domain unit circle?
why does it matter? we don't deal in the performance of unstable systems
Stable systems can have zeros located in the right-half plane / outside the unit circle.
Unstable zeros are not desirable as they cause an undershoot in the response.
Awesome video man ! btw, did you hear about the rumors of state space ? they said that a guy called brain will make it in the next video !! :D :D :P @Brian Douglas
State space? I almost forgot!
Brian Douglas oh no ! Please don't forget ! By the name of control theory we request the state space video to come out :D
Yay! :DDDD
Wa vs Wd???? What was Wa? What was Wd?
Am just gonna say *R^3* and i'll retreate slowly...
Don't like your video, you jump around to much.
When you say woops I made a mistake and change parameters, you lose your audience.
