Sketching a root locus by hand can be done by following some simple rules. However, more important than actually being able to sketch to plot is being able to use our knowledge to design compensators in the S-plane. Understanding how poles and zeros affect a closed loop control system allows you to predict what you need in order to build a stable system just by looking at the root locus.

If you have any questions on it leave them in the comment section below or on Twitter and I'll try my best to answer them.
I will be loading a new video each week and welcome suggestions for new topics. Please leave a comment or question below and I will do my best to address it. Thanks for watching!
You are the reason many future engineers pass control systems and receive their degrees. Please keep up the good work!

"Each open-loop pole has its open-loop zero friend and they draw a path between the two. And if a pole or a zero doesn't have a friend then they go off to infinity searching for them."

idk why but feelsss
he got me there too
0.0 .....poetic fucking engineering tutorial *.*
LOVE IT SO MUCH
Teaching done right. People learn so much more easily with examples like these
That one single line got me though
poor guys, forever searching for a friend. so sad D;
Some of the lecturers from my University does NOT deserve their salaries. Thank you.
+Lester H They get paid mostly for the research they do not how they teach. Most universities dont care about their profs teaching abilities.
if i happened to be a lecturer of this subject then i'll just show this channel to my students and enjoy my salaries lol
Are you talking about india?
took 14 minutes on here to understand this compared to 32 lectures from a PHD of 22 years lol
loool same here
Colin Cassidy Exactly !
Colin Cassidy exactly!!!
Same!!!
I'm so glad i can find this video before i study that much!!
thanks brian
One of my favorite controls books is "Control Theory Second Edition" by JR Leigh. There are a lot of great books that describe the theory and show you the math, but this book explains most of the concepts in words. I think engineers can get a good understanding of "why" the theory as opposed to"what's" the theory from this book.
you are a legend, you make this very easy.
are you a practicing engineer?
can you post the notes you used in the videos so we can use them to study?
Hey Mr.Douglas, thank you so much for this textbook recommendation (& all of your lectures of course). You are a real G
This channel has genuinely made me want CZcams to implement a "Buy this guy a beer" button. Your videos are all so damn straightforward to understand, and you've taught me more in two days than I've managed to understand from 19 hours of lectures on the subject. Thank you so so much.
I just wanted to say thank you for the informative videos. They are doing a fantastic job at helping me prepare for my final and are vastly more interesting and explanatory than my book or lectures have been. Keep up the great work!
I've been trying to understand root locus sketching for hours and this video made me understand it better than one whole semester of lectures
This video was uploaded 10 yrs ago but still impactful even today. I was struggling to sketch root locus. This video helped me pass Control Systems, my final elective for BSc Electrical Eng. Kudos to you Brian, you've earned a new subscriber.
I have exam about Control Engineering in University, just as you predicted and Your set of videos explained everything so much better than in the real course! I appreciate so much that people like you exist! You have great ability to explain rather complex things in a clear and structured way! Thanks a lot and wish you good luck in everything you do!
Simply amazing, control systems has been by far the only major tough subject in my degree and your lectures nail it greatly! Well done and thank you!
So much knowledge in just one video! I dont even know what to note down, I mean everything you say is just important. THank you
Really concise and sufficient explanations in all of your videos I've seen so far. Excellent work, you have helped me so much... no need to go to lectures now, awesome content you are sharing with the world. Thank you
Your way of teaching is phenomenal and extremely easy to understand even though the material is not simplified!! Applied engineering with examples is what we need! Thank you!!
Very useful. I'm a Canadian engineering student and this has clarified basic things my prof has ignored!
These videos are so helpful! My introductory controls professor was terrible and he tainted the subject for me forever, but this is helping me so much! Thank you!!!
This is a crystal clear explanation. Although I'm not English speaking, I learned so much more by watching your rather than the syllabus I'm using! Thank you so much!
Thank you so much for these videos. I haven't heard control theory explained this straight forward and easy to understand before.
God bless you Brian; thanks to your way of teaching, I am finally getting it.
i would like to thank you for your awsome videos!! eventhough english is my second language and i live in Saudi Arabia, i fully get the concept behind your lectures because of the beautiful way you represent them
again thanks alot
Well done. All your videos are very informative. I didn't think I'd find such a straightforward video on what I thought was an obscure topic for youtube. Cheers
your videos are AWESOME, I didn't learn a thing in class, but these videos saved my ass in the final exam.
thank you so much
the best lecturer ever! only 13 minutes covered 3 lecture(120min) of our lecture
Your explanations are very very clear.
Thank you so much
This is amazing. Greatest teacher I've had the pleasure of listening to. Thank you
Your tutorials are sooo useful, I wish you covered the subjects in all my other papers as well
I have learned so much from watching your videos. I'm taking a controls course right now and I thought it was awful until I came upon your videos. The material is extremely cool but my professor teaches purely the mechanics and it's frustrating to not understand how this stuff applies to the real world. You do a great job at making the material interesting and I can't thank you enough for taking the time to make these.
my professor found a way to make this seem outrageously difficult
thank you very much Douglas! I'm very expected your new videos!
I'm a student at university. love you sir. will watch all your videos. really helpful, informative easy to understand and time-saving. thank you very much
Lifesaver. Thanks for such clear and well structured tutorial.
Thanks Brian. You were right in your assumptions, I have an exam coming for control systems course. Thanks again. That's a good video. Thanks.
Thank you so much sir. Your way of explaining things is exceptional.
These videos are pure gold!
I'll always recommend this channel for whoever is studying control systems.
Really excellent videos! Thank you for the clear explanations!
An instructor who explains why what he is saying is important is an incredible tactic that unfortunately very few use. Amazing.
These are the best videos on net regarding control systems. Please upload more videos.
Best thing my Control System teacher ever did: recommend this channel.
thank you! you have opened my mind!
Thank for your video. It's so greater, make I wanna learn about it more !
Finally. Finally I understand how Matlab knows where to put k. Thanks a lot.
Excellent video! Great use of colours! And nice handwriting!... But most of all, excellent presentation of ideas... We need more teachers like you in this world!
Beautiful explanation, you are making the world smarter.
You are the saviour, man! Lots of love for you!
These videos are GREAT! Much better than the class I am paying an outrageous amount of money to take
These classes are great, thanks!
Your video just saved me hours of struggling, thank you.
oh my god, you saved my life!
mine too :D
short yet very good.....great work...
very nice explanation! great job! thanks a lot
Hi Brian...awesome..creative...crisp...what r u..an Artist? Engineer? Teacher?...I think a combination of all...thoroughly impressed...
super
This and part 2 are excellent videos helping one grasp the concepts of a root locus sketch. However, I wish the comment at the end of part 2 about this not answering the university required questions such as intercepting the imaginary axis etc. was mentioned as a disclaimer in the beginning of this video. I am grateful that I now understand the principles, but I now have to spend additional time researching videos that explain those other rules, which I will need to know for exams (but never again in real life, thanks to Matlab). Still a big thumbs up!
THANK YOU SO MUCH FOR THIS, I FEEL SO ENLIGHTENED
Thanks for putting up this content!
Thank you very much! This is a very clear and useful video. Keep up the good work.
These videos are awesome! Excellent job and keep it going!
You saved my control journey at ust. Thanks 😎
U are the best teacher for this subject .
Great videos! Appreciate the content. I like playing around with digital graph parameters more even though that’s a modern luxury.
Awesome Tutorial. Thank you very much!
Just amazing! Thanks for this video lecture :)
Thanks so much for these!
English is my second language .......I like the way you explain it at 8:55 when you say by multiplying with infinity you put more importance on Q(s) THE WAY YOU USE DOMINACE AND IMPORTANCE is very much nice
These are pretty amazing thanks for the help
Such an amazing mentor. Thanks Buddy. You are my new hero xD
this is just great man thanks for this!
Thanks for the great lecture video 👍🏻👍🏻
mate I don't know if its cry of joy or the fact that my professor is not the best and I might fail but I thank you for the explanation, you are a king!
I cant thank you enough for these videos..
Our professor who graduated from MIT failed so hard on teaching this course. HUGE thanks and you are not even charging anything while our university asked for $37000 CAD.
I didn't like control system, but after seeing these videos i started understanding it. I am starting this a day before the exams and I think these videos helped me a lot. Do you have a series about signals?
Thanks for explaining the purpose behind doing stuff, it's the only difference between being able to vomit answers in a test vs. actually knowing what you're doing and why (which is what's needed out of education)
I love you
As always, excellent. Thanks Brian.
im so happy for this ..... thank you
Great explanation! Thank you!
Brian Douglas is the greatest!
wow watching your videos for 30 minutes took away 3 weeks of confusions
"Each open loop pole has their open loop friend and if they don't have a friend they go out to infinity searching for them" those were probably the most beautiful words i have heard in my engineering education so far!
You are great. You help me so much! Thank you
You really save my life!!!Thank you!!!
You've earned my subscription.
Thanks for the initiative.
Thank you very much it helped me a lot
man, these are SO helpful! thank you!!
Thanks for sharing...understand more clearly now
You made life easier and interesting, again! Thanks!
Thank you! You saved so many engineering students like me to pass their courses.
real champ'! that was supper helpful! thank you very much!
great lecture series///you are the best..
Fantastic job as usual.. you are awesome
Great!! Crystal clear...
You're doing the Lord's work, Brian.
This is excellent sir. I guess you could teach many subjects in electrical and control engineering. Keep it up and thanks.
amazing video and explanation
amazing explanation!!!!!!
Brian you are awesome!!!!
That's an amazing video!
never understood this in class like I did after watching this video.! thank you!
Great video! Thanks! Greetings from the Netherlands
