Thank you so much! This video is extremely helpful, not only because of your patient and explicit explanation but also because it is almost the only video about the Nyquist plot that goes so thoroughly and deeply into examples. Even my favorite channels only gave me basic concepts. This video just saved my life.
i can never thank you enough for the help you have given by uploading this video!! this concept is a little difficult to understand if tried from a book. so thank you so much!
Thank you so much, I only went through the parts of the video I needed, but this is the most helpful video I've seen to help me for a class! I've tried watching videos for other classes many times but I barely understand them. This was very informative. Ready to ace that final tomorrow!!
great video! helped a lot with a further understanding, The only suggestion I could make is adding links in the video description for the individual steps you're taking, seeing the video is pretty long, and the steps can be hard to find!
Hey buddy! I found your video very clear and helpful. I just found a little mistake (I guess haha) while re-doing the exercise that you are doing at 1:44:20. The condition for stability holds for 2*K, instead of just for K. So the real condition for K to achieve closed-loop system stability is actually: 0
I have the same problem as many persons here, when you calculated the angle when w=1 you got -135 degrees, and when I calculated I found that the angle is -71.6 degrees... What happen??? I was checking this result many times and I got the same result. Im an Electronic Engineering student, keep making this excelent videos!!! Greetings from Mexico!!
thank you very much for your effort. In my particular case however we get the factors of s not in Numbers but in variables . For example: K/(T1s^2)*(T2^2s^3+1) one time for T1>T2>0 and one time for T2>T1>0. In this case i cant apply your method, because i cannot calculate the specific magnitude and angle by having variables instead of numbers. What method should i be using in this case?
I think in example 2, the negative real axis crossing should have existed which is -1/2. So the system isn't stable for all K>0. If I did not mistake. Thanks. By the way, good job Yan Cui.
This is by far the best Nyquist Video I have seen. I wish you had more videos on control theory!
The most helpful Nyquist examples I've seen yet. Thanks a lot.
I cannot thank you enough, man!
This is by far the best video on the subject

By far the most understandable Nyquist plot and Nyquist stability criterion video I have ever seen. Thank you very much!
The best video to learn Nyquist!
i can never thank you enough for the help you have given by uploading this video!! this concept is a little difficult to understand if tried from a book. so thank you so much!
very well explained. So understandable even for the beginners. I don't mind paying for this sort of tutorial video. Thank you very much!!

Very detailed and step by step examples. You have my thanks!
Awed by your versatility, the best video on nyquist plot.
정말 감사합니다. 나이퀴스트 강의 중 제일 최고입니다.
The best of nyquist plot video !
Thank you so much. This is the best video i've ever seen on nyquist. U saved me
Thank U. You saved my last exam!!
Best video lecture for Nyquist stability criteria . Thank you
I'm preparing my last final exam (electronic engineering), I think u saved it! I'll return in may and comment with the result.
THANK U!
Whats the result
omg bro, thank you. You turn the nyquist concept more easier to understanding
This material helped me prepare for an exam. Thanks!!
You saved me, Yan! Thank you for this video!
Thank you for this video sir. I learned a lot. You are a perfect teacher.
I loved this video from beginning to end ,thank you so much!
Was an awesome help in understanding and being able to use nyquist. Thank you a lot!
I am studying electroengineering in germany! You helped me a lot, thank you so much... okay^^
From Hacettepe University in Turkey as Electronics Engineering student I'm so glad for ur teaching sir, thank u so much!!!
Thank you very much !!! U were so patient to made this video...u made each part very clear !!! thanks again
Best one great
No complicated explanations
wow...you have put in a lot of hard work........thank you so much
Thank you very much. This is a brilliant explanation!
Thank you so much sir....ur lecture was superbly clear... It cleared my concept..doubt...thank you so much sir.. Hats off to your lecture.
the most amazing video on this topic!!!!! you literally saved me
Thank you so much. This video helps a lot. It is super clear. Best lecture for Nyquist plot.
thanks for the step by step solutions, this helped me so much
Thanks for your great and detailed lecture.
thank you so much for the explanation. the best out here on youtube.
great video! helped a lot with a further understanding, The only suggestion I could make is adding links in the video description for the individual steps you're taking, seeing the video is pretty long, and the steps can be hard to find!
GREAT HELP! THANKS FOR YOUR EFFORT!
A REALLY HELPFUL VIDEO> BEST I HAVE VIEWED ON TH-cam THANKSSSSSS
Amazing explanation. Thank you!
Amazing video sir !! Thanks a lot
Thank you so so much... There is no better than this video!!!

nah buddy its only 1/0.18 cause u considered k=1 at first. had u considered k=2 then it would have been the case. cheers.
Thank you! Great video!
Thanks for the lesson, very talented to teach :)
Thanks you it help me a lot am studying chemical engineering in Zimbabwe.
Great video, helped me make sense of it all
Really helpful.....Many many thanks...
Thank you for Your video, King. P.s. Happy New Year)))
Thank u very much ...it cleared all my doubts ..☺
Tuve que buscar videos en INgles para aprender ya que no explican bien los que dan tutoriales en español. This the best video about Nyquist
Best of Best 🙏🏻🙏🏻🙏🏻♥️♥️♥️
This saved my life.
You are teaching from lot prof. of universities .You have a very unique style 👌
excelent¡¡ you are helping a spanish student, congratulations man¡¡
Seems he's helping 2 now hahahah ;)
A very clear explanation thanks a lot
thank for your help, the best video ever
Very good!! Helps me a lot.
lovely... thanks man.. you saved my day
perfect explanation!
Hey , it helped so much thanks from Belgium :)
Cheers, you should do this more often !
very clear example. TQ
I have the same problem as many persons here, when you calculated the angle when w=1 you got -135 degrees, and when I calculated I found that the angle is -71.6 degrees... What happen???

thank you so much, this really helps
many thanks.you did a great video
Thank you Yan!!!
Very nice video, my friend. You deserve congratulations for sharing that knowledge. Thank you, Yan Cui san!
I'm watching it again and seeing how well you explained it all. Very, very well! Thanks a lot!!!
Thank U Sir !! What a video
you are the best , thank you a lot
Very good!
very clear and helpful.
thx.
thank you. this helped me so much
Helped me so much !
Thanks so must sir. engineering student from University of the South Pacific.
Thank you so much Yan :)
Only good video around! Helped me a lot!
thank you very much it's very helpful
Also support on determining the phase and gain margins using the Nyquist plot. More also is support for Bode plot
Very good explanation. I had to jump around alot though, first example took over 30 minutes.
thnks alot..it helped so much..i am an engineering student from india..thnks a ton for dis ;)
+asmita bagchi Same here !! It helped me so much!!!

EXCELLENT!!!!!!!!!!!!!!!!
Thank you so much! 太谢谢你！
thanks a lot...helped so much...thanks.
thanks , it helped me a lot !!!
thanks for go through the details

Thank you so much!
Guys at 1:13:58, can I say that the angle is equal to: -arctan(w/(w^2/2)) = -arctan(2/w) ? I don't get why we have to do the 90 degrees, etc thing?
thank you !
Thank you a lot
Just saved me 🙏 🙏 🙏 🙏 🙏 🙏
I think in example 2, the negative real axis crossing should have existed which is -1/2. So the system isn't stable for all K>0. If I did not mistake. Thanks.
By the way, good job Yan Cui.
great explaination
Great thanks!!!
when i solved exp1 when real part=0, w=0.53, is not -0.18 please cheack your answer..thanks please answer me
Meraviglia !!
very helpful :)..thank you .
Thanks a lot!
thank you so much.
Best explains
thank you so much it really helped me out
am electrical engineer from Iraq
