In under 14 minutes you explained this better than my prof in 3 lectures. I am forever indebted to you . You are the real MVP.
Exactly.....u thee boss Brian
Exactly mate.. I was going astray then suddenly I found this video.. Nice work done..!!
Not to mean that he doesn't explain well but one is able to understand this fast because you got 3 lectures before, all people seem to forget that
That is why Brian Douglas is my god. I will follow his teachings
agreeeeeeeeee
Everytime I search a topic in my controls class on UA-cam i cross my fingers and hope there’s a Brian Douglas video lmao
Still helping people 4 years later, what a legend
Less phase and gain margin both are decrease stability or something different?
5 years later
@@harishchoudhary1441 yes, this will be still stable but the margin will be less. Will go quickly in the unstable mode for any undesired event.
6 years later.
7 years!
This video is 7 years old, free and still provides a better understanding then the lecture content that I pay for at my institution, thank you so much.
I've been struggling these years to understand how phase and gain margin works and in a 15 min video you clearly explain it in a very dynamic way, really good content!
Hi Brian. It's been about four years since I took any control systems lectures, but even though I work in a different branch of EE, I occasionally spend time reading up on previous topics I haven't seen since my undergraduate career. Reading through Nise's book again has been a trying and dry task, but watching these videos has shed serious clarity on the subject and I'm understanding it better than ever. Just wanted to say thank you for making these! I love a great engineering channel!
Thank you, sir. I'm studying electrical & computer engineering and watching your videos really helped me a lot. Keep up the good work.
I've been reading papers for this so I can understand what those two are for my master's thesis and you explained it perfectly in 14 minutes. I can't thank you enough!
This whole series is FANTASTIC!!!!! After numerous books and lectures, I did not quite get it. Control theory is starting to make sense, but more importantly starting to help my practical design efforts in power electronics.
Wow, this Channel is the discovery of the year! What a genius way of explaining this stuff, hats off to you Brian, lovely work!
Man to put it simply you are a legend! You helped me understand the true meaning of a lot of things in Control Theory. You explain things that very few people on UA-cam touch accurately and professors who teach the subject are mostly bothered with the maths rather than the true meaning of things. I owe you big time!
I am studying for my PhD qualifying exam in feedback control/linear systems and I can say this is as of yet the BEST explanation I have ever seen on this topic :) Thank you so much
This is hands down one of the most brilliant, simple, no bullshit videos I've ever seen. Thank you so much for this. Perfect utilisation of 13 minutes.
This explanation was incredibly clear, and helped tie up so many loose ends. Thanks so much for making this!
Mate you rock! I've been able to grasp all the concepts from your videos a lot better than from my professor in almost 2 months! Thanks a lot
I really enjoy your videos .. when I'm tired and bored to read a book or solve problems .. I just relax and watch your videos .. God bless your soul :D
I can't pass without saying "thank you". I think you are gonna save me for my System Dynamics Control exam tomorrow!
Thank You
Great videos Brian, I watched them throughout a control systems course and they really helped with intuitively understanding the topics.
So detail-oriented tutor! Love you so much. Thank heavens for your existence in the world!
AWESOME!!! that is absolutely the best thing i ve ever found as a teaching video!!
I really wish you had made this viseo last year. Your lectures makes so much more sense. Keep up the good work.
your explanation and drawings are a huge help to get the idea of gain and phase margin ! It is just so intuitive. thanks a lot!!
Whatever you do, do not stop making these videos. Definitely the best video I have seen regarding the subject.
First video I've seen from you, a schoolmate recommended your channel to me. Incredibly helpful! Thanks in advance for teaching me! :D
You are very thorough in your videos, thank you so much!
I was waiting for this video! Such an important topic! Thanks Brian!
man you are a life saver. i have been watching a lot of your videos and the all have been helpfull to me. big up man
YES! Thank you Brian. This is exactly what I have been trying to figure out for a long time.
Awesome work! The explanation, length, speed, pronunciation... everything is perfect! Thanks a lot!
Brief and to the point. Very helpful. Thank you for this amazing short lecture.
Found this series reviewing for my FE/PE exams! Exactly what I needed to get back on track.
Super awesome explanation, saving me from confusion. Thanks Brian!
impressed by the quality of your videos, great stuff! thank you very much for your help!
your videos are helping me very much in understanding control systems. This is really an intuitive approach. Thanks a lot sir!
You are the mann!! I've been looking for this information in a clear way for so long... And I really like the pase. Somehow I think this is easier to get, than if you would have explained it at a slower rate. Thanks! Only one thing I would have really appreciated is if you had mentioned the "crossover frequency" in the video. Or is it in one of your other videos?
Wow. NOW I understand this. I will be watching the other videos also. Thanks for this fantastic lecture.
Amazingly explained thank you so much! I was so confused when I studied this and then I found this!
Man. Your concepts are crystal clear. You nailed it sir. 👍🏻
this was excellent. exactly the level of detail I needed. Thank you!
Brian Douglas, you are a true life saver! Thank you for your great videos! Wish you the best!
Thanks mate, really, thank you so much. I'm an engineer and I studied that thing more than 10 years ago. These days I need the information again. After searching web for hours I was frustrated. I decided to go on youtube as a last resort and tadaaa! your video made everything clear in 10 minutes. I haven't watched the matlab part yet but I've decided to add a comment!!👍
Your explanations are amazing!! Please keep it up!!
Thanks again Brian! It's not many people can make you laugh while clearly explaining control theory!
Thank you so much for this video. It makes the concept of margins so clear !
This video is so revealing for the concept of why use of bode diagrams - I LIKED IT - ...… thanks a lot Brian =D
4:11 wow that analogy couldn't have been more perfect.
Bioengineering student here... you sir, just saved my ass!!. There are VERY few people who can explain this subject with enthusiasm and absolute clarity. Sadly my control systems teacher is not one of them. A million thanks from Bogotá (Colombia).
Awesome explanation. It cleared so many doubts. Couldn't have asked more on this topic with Matlab demonstrations. Thanks a lot again.
You make the world a better place :)
I really agree with you...!
Wow! That's f***ing brilliant! Gonna binge watch your playlist before my exam in a week.
Amazing work mate!
Best explanation. I would even say your vids are a good introduction to control. Of course having the mindset that later these things will go into much more detail, but just to grasp some overall concept of what's going on. Most lecturer's just jump way way way into the details and the CONTEXT is lost. thanks Brian.
Great video Brian, looking forward to the next one.
Brian deserves the Nobel prize for teaching!
Totally agree with you.
hey douglas u r just awesome !!! It totally cleared my doubts !!
Great video Brian, thanks for the explanation. What about a short explanation on the sign of gain margin, in particular a negative gain margin example.
This video is VERY helpful. Thank you for such a well-made production!
My advisor had me skip classical controls and go straight into multi-input multi-output LTI systems, so suffice to say I was very unprepared. Thanks for clearing a lot of this stuff up!
Dear Brian, your tutorials are all excellent!
Makes me want to pay more attention in class 😂. I genuinely felt like I learned something just now. And thanks to that you made me more motivated to do my work. Thank you !! :)
Great job! Your lectures are just amazing and praise-worthy.
This was much much better than what I learned during our lectures. Thanks a lot
thanks for taking painstaking effort to put this together!
Woww,I have never found such an amazing video on youtube ,so great illustrations ,please help us by keeping it up
Your videos are amazing. I've learned so much about control systems from you compared to my professor! :)
This video is simply the best of the videos I have watched on this topic. Thank you very much
you are a genius at tying these concepts together ty ty ty ty
Great video, I have understood it very well, and I was never taught this in a class :)
Very well explained... Been studying control system for a long time and yet this video brought the most clarity'
The excellent and clear video we all needed. Thanks a lot!
this is so far the best explanation to this topic. Thanks!!!!
Till this day, after over a year of courses partially dealing with bode plots, I never understood the purpose of Gain and Phase Margins. THANK YOU!!!
PS: You def got yourself a Like and Sub!
Thanks a lot man. You really helped me understand some things I never trully understood. Thank you so much.
one of the best videos I have ever watched to understand Bode plot
Thank you Brian! outstanding lectures. Amazing job.
Thank you so much for this! So much more clear than my professor's lecture!
Rofl 5:12 like a boss. Thanks B. Douglas for another fantastic video- your fast paced and comprehensive lessons are wonderful to watch, even if I am not really part of your target audience :)
You found it! :)
what was it?
This video is so good! Thanks, Brian.
Im a South African student studying Electrical in India and its really tough and its very difficult to find proper english videos and i happen to stumble upon your channel thank you and hats off to you👍🙏
wao! you are So exelent. I mean to put the entire content as general/global then you explain what you want to get from it and then the conclusion. I understand everything and my mother tonge language is Spanish. If I could I would do something in change for you just by the fact that I understand Control theory because of you.
Thanks for the simplest and awesome explanation of a complex topic 🙏🙏🙏
Congratulations Brian! I wanna buy your future book! ...I have a question, what about stability in systems with more than one phase margin?
Great Video :)
I would like to know more about the special cases:
what happens when the Gain graph doesn't cross the 0dB line, and\or the Phase graph doesn't cross the 180 degrees line?
how can you determine the stability then? (given that you can't calculate the GM or the PM or both?)
Thank you so much for making these!
Thanks Brian! You're my hero
i was waiting for this lectrue. tnxx a lot douglas.:)
This is spot on. Fantastic job.
Dude so very helpful. You would kick ass as a professor if you ever went that route. I would take your classes
Excellent course! I'm providing similar material but tackling it from a different angle. Extremely important topic!!
well explained and helped me in a quick understanding.... thank you sir.
Simply Wow!! That feeling when you understand it so good!!
it definitely helped to clear things up a bit! Though i hoped to find analytical examples in calculating this. Because we can't use matlab on exams :(
I like your video. They are clear and effective. Thank you and please make more.
Yet again another fantastic video!!!! You're a lifesaver!!!
This teacher is literally legend
The "story " about Gain and Phase Margins I think it from the most difficult concepts...to say why and where 1 and -180 coming from and so on...Always all things are more obvious if you know the story...So imo it was so clear explanation!Good job..keep going like this...thank you!
Amazing...took me real long to reach this helpful video..wish I had seen this earlier
thank you for that brilliant explanation I really appreciate it
I could not find a better explanation anywhere on the internet!
Beautiful and concise explanation. Thank you so much.
Great video. Cleared so much ambiguity in this topic.
