You not only make me understand, but also make me marvel at the beauty of the stuff you're teaching. You are a brilliant teacher! Thank you so much for taking the time out to make these videos and helping us struggling undergraduates with something that can be so simple, but is generally taught in a way that makes the material inaccessible and scary.
The reason this is so good is because of the example program he made rather than theorems that are very hard to read because they skip all the derivation steps and just say they are trivial and we should do at our own time.
What if the RHS zeros of (1+G*H) are compensated by the zeros of G ? Than you will not have Poles in the RHS of the closed loop system CLTF = G / (1+G*H) Is this case even possible?
I have placed the two scripts I wrote in Google docs and placed the link in the description. I have not modified the existing Nyquist function in Matlab ... it was just a bit of movie magic! After the plots came up I modified them a little by making the lines thicker and such so it's easier for you guys to see. I just edited that part out.
You're an absolute legend, I failed my summer exam in control and I have my repeats in 4 weeks. Your vids are saving me, and I think I'm finally getting the concept of CONTROL. I wish you the best in life, sincerely.
You helped me grasp control theory like never before. I now think like a control system engineer. Brian, your dedication to teaching is truly appreciated. Just as scientists advance knowledge, educators like you ensure its transmission. Thank you for your invaluable contribution.
You must understand that you have a unique gift of God that you can explain things so purely. I feel enlightened by the level of insight you present. Thank you, Sir.
You are an amazing teacher! Thank you so much for making this amazing resource publicly available. You are responsible for many engineering students developing a real understanding of important stuff
The best explanation of the Nyquist plot. I gave up this topic but thanks to you now I can imagine what is the Nyquist plot and why it even exists. thanks, man.
I'll be another drop in the bucket when I say this, but I have to say it. This video is phenomenal. All of your videos that I've watched so far are amazing. I think you're the reason I will pass my control systems course. Thank you for your work.
Amazing! The reader for my system control class dedicated a whole 400-orso words to Nyquist diagrams... So I am glad to have found someone explaining it to this degree of clearness!
This series is fantastic. I wish more people who taught Controls could communicate the concepts as effectively as you do in your videos. Keep up the great work!
Hey man, just wanted to say your online classes are worth 10 of my brain-shrivelling books, I wish I had a teacher like you for every class!! Keep it up, you make all of our lives so much easier!
Before learning the maths behind a topic, its very helpful for a teacher like you to explain the reasoning and overall picture of whats going on. I feel my knowledge is incomplete without watching your videoes. Thanks for the great work!
Today I just skipped my lesson in Modern Design of Control System, because i didn't understand the previous ones about Nyquist, so it wouldn't have been useful going to lesson today. Thanks to you, maybe I can go to the next lesson! Love u man
OMFG, I really, really enjoy the way you explain. I know there are too many people who are not from an English speaking country and watch your videos, just like me! Regards from Argentina
Thanks alot, Nyquist criterion was a topic I hated because of lack of understanding, I tried many resources including some reference books, but I didn't understand it. Now because of your beautiful explanation, not only that I understood it really well, I could appreciate the beauty of the concept, thanks again
I clicked here by accident but stayed because it sounded so interesting. Literally had 0 knowledge of the topic at hand, but you were such a good teacher that I feel like I learned something anyway haha
Absolutely amazing videos. I have understood far more through this 17 min video that i have in an entire semester that spans 5 months. Thank you very much.
Awesome explanation of the so smokey Cauchy Argument principle that most text books fail to explain, making it impossible to grasp the real thing! Even 20 years ago when i studied this at the university they gave us quite a smokey explanation compared to this one. Great job! Thumbs up!
wah....was having so much trouble with Nyquist and this one video (well ofcourse with some previous knowledge of the Nyquist plot) clears most of the things! great work Brain!
I know I know! I have the script done and will try to draw it and post it tomorrow. The end of summer has been busy and I've been slacking on these videos :( Best of luck with your exam, I'm glad my videos are helping.
Wow! Amazing. I am speaking for everyone when I say could you upload the 2nd part because we all love you and need these videos in our lives. You should be paid for what you do!
I came to your channel like a year ago to study bode plots and it was so good I subscribed, today i was seraching for nyquist plots and not only you were once again flawless in your explanation but I also found the control theory map that my teacher used to present the module. You are influencing both students and teachers around the globe, thank you very much and greetings from barcelona!
Thanks for making these videos, Brian. I'm laid-up right now with a broken ankle, so I'm diverting some of my couch and raised-foot time to these lessons. You're really good at driving home the concepts. Just an idea: As a recent EE graduate, I'd like to see a video where you design a simple controls system or model or whatever, but without regard to a generic student. Just a straight-forward, "thinking outloud" version of you working through a problem. Just an idea.
You've almost saved my life, no words can describe how grateful am I. If you can add some videos about z transform & discrete systems control it will be awesome because my teacher sux :D.
I don't knowif your explanation is right or wrong, but I know it's awesome, I don't know why teachers whom I pay lots of money don't explain things like you do. Big like and all the best with your book Brian.
Off topic but i would like to know how did you make that interactive .m file.Is there any built in some sort of app or plugin for such moveable demonstrations ?
Hi Brian, following question: Is it correct that Z=N+P tells me for my closed loop system to be stable for every Open Loop Pole on the RHP my nyquist plot needs at least one CCW encirclements of -1+j0?
isn't there somthing essentially paradoxical about needing to know the specific positions of the poles and zeros in order to map to the w-plane, when the entire point of doing so is that the output in the w-plane illicits infomation only about if the zeros lie on the right hand side of the plane. This sees like you loose infomation rather than gain. I'm obvisouly wrong, but could somebody clear this up??
I'm electronics engineering student and I have to say that because of your tutorials even my smartest control&automation mates at the college will lack the understanding I'm getting here of this basic stiff material..! No one cares for math as it's pure interference with the core of engineering even those elder professors. even if I fail the final for second time, I'm extremely interested in watching this course. Hope you make more content on different areas of "practical control" like microcontrollers and so on. Greetings! 💘
I used to just record the whole screen and crop it in post. Now I use Capto and can select a region of the screen. Process is here: engineeringmedia.com/my-setup
