pretty sure you learn Routh-Hurwitz together with root locus and other stability criteria in one single class. That said, I had an Indian lecturer whose accent was not comprehensible to me. I would love subtitles.
I had a terrific controls professor in college who taught this stuff, but I was not a very good student in this topic. Now decades later in the latter half of my somewhat successful engineering career, I am back to muscling up on controls with this excellent series. Thanks Brian Douglas!
I wish you would continue to share videos. I think As a Control Engineer candidate in Turkey, I say, you are explaining better than you were told at the university. So glad I have you.
Thanks! Even though I don’t post on my channel anymore I still make videos for the Matlab channel. You can find them all here: engineeringmedia.com/videos.
Two lecturers * 2 hours each to explain Routh-Hurwitz Criterion in my university. summarized under 13 minutes in this video. Seriously this pattern of filling the array is much faster than memorizing the equations for each row!. I appreciate your hard work.
Your pattern approach is so good, I appreciate it. Memorizing equation without knowing its logic behind them is worse than memorizing the pattern without knowing the logic behind it.
Wonderful. I am teaching to University students by listening to your lectures. A must watch for everyone trying to understand Control Systems with reasoning.
you've made it 10 times more easy than how my teacher explained it! now i'm seriously mad about how much i pay in tuition fees for researches how want to teach but don't have the ability to deliver an info!
I'm doing my Feedback control homework right now, I have found your technique to not only be simple, but nowhere near as convoluted as the book and my professor makes it out to be, for that I thank you greatly!
Brian, you are awesome! I'm a novice at control theory and I tried reading up at-least 3 books to get my basics right. None of the books can match up to the simplicity of your teaching methods. Thanks for all the videos. Keep em coming.
Robert Mandell, I think the same you do! Brian, tus clases son excelentes, la manera de transmitir la información de una manera significativa, concisa, oportuna y gráfica. En verdad muchas gracias por explicarme de una manera tan eficiente!!!! You're a great teacher!!!
I just watched a 45 minute lecture where my professor loosely went over the math, assigned 1 Routh Hurwitz problem for homework and said 1 example will be on the exam. This theory is sort of antiquated now what with Wolfram Alpha now, but without this video I would not have been able to do the damn homework. Thanks
You are really excellent at explaining this, my state university controls prof could never dream to convey the Routh, root locus or Nyquist stability methods as well as you have in your videos. Thank you very much!
Hi Brian, first of all, great vids, they help a lot. All of your real life examples really make a difference understanding all the concepts. I would like to suggest you to "fix" the playlist order. This video talks about some concepts we have not heard about yet (if we are following the playlist order). You should put the "Stability of Closed Loop Control Systems" video before this one so we all can understand it all. And thanks once more!
If you noticed a spike in likes, views or subscriptions, then I send regards from the Singapore Polytechnic! Your 3 videos on Routh-Hurwitz Criterion were used by many engineering students here to learn about the Routh Array Method to determine stability of control systems during a "Home-Based Learning" week. We think your explanations are brilliant and memorable!
You are a legend! Most useful, easy to understand straight forward lectures ever! Helping me heaps with my final year thesis of designing a inverter controller :-)
Though this video is nine years old now, I also think it's still one of the best! Everything from the background knowledge provided to the crispness of the explanation and the tidy handwriting was wonderful. On a side note, I think the point about a sign change in the original polynomial is related to Descartes' rule of signs; specifically, if there is an odd number of sign changes, then there must be an odd number of positive real roots. In any case, thanks again!
you are awesome! you manage to explain the example together with the theory fully in a small amount of time! that's how any youtube educator should be, make it clear and concise, thanks mate for your effort
You dont understand how much you made my life easy with that this is all i wanted to understand im actually writing you it while studying for my exam at this subject also i saw the video about the P , Pi , PID Controllers i found it very helpful hope ill get A , A+
these lecture are awesome, cause in classes we are only do math calculation and match the answers but here we know about the real meaning of control system n how math tool use for simplified the problems.
I have my exam tomorrow and this video literally taught me what I needed to know so quickly. Now I went from knowing nothing to be able to gain at least a few marks.
I wish I had money to pay you! Unfortunately my useless university has taken all my money and left me with nothing but confusion. You are such a champ!
Thanks for uploading. I've been having problems on how to get the 4th rows and so on but with the pattern introduced in the video, I now understand. Thank you. 😊😊
Hi Brian. Your Lectures are great to fill some gaps in my study (especially when lecturer said to study Routh-Hurwitz Criterion by ourselves at home), but I have to correct you. At the beginning (0:40), you say that the roots of characteristic equation are the same as poles of the TF. That is not true, because when you create a TF, you can reduce zeros and poles (eg. in (s-1)/((s-1)(s+2) to 1/(s+2) - stability change!) and then it is NOT the same. They tought us the same at Theory of system but corrected at Automatic controll ;) Also a little mistake at 3:30 - I believe you wanted to write "without solving for the roots" :)
Excellent explanation; my Vibrations 1 professor skipped over the Routh Criterion because he said that "it's no longer used in industry, and has been replaced by computers". However, I'm taking Vibrations 2 (an elective course), and the professor in that course assumed that everyone learned this, and now had to modify his lecture to accommodate that fact. This helps with the homework problem... :P
hi brian, these video lectures are amazing as I am using them in substitute to my own professors material. I am learning with ease with you! If I make one suggestion: I think it would be astoundingly helpful if you post your notes so that they are downloadable for students! I find that there are a lot of details in the notes that are essential and I am a slow notetaker; therefore, if I could download these notes then I could follow along with you at a much more efficient pace! Anywho, thank you!
Leaving a comment for solidarity. This nine year old video is but a hallowed temple, for which each passing engineering student must stop at to reflect upon their travels. Thoughts such as "why the hell didn't I just pay attention in lecture?" and "hot damn, this guy can explain a concept" echo through these timeless halls, set under neon highlighter scribbles which pass like digital winds and carve deep grooves in the minds of sleep deprived undergrads both past and future.
Update: I've passed the exam of "control of energy plants" and I think it's 70% thank to this videos. In particular I managed to explain to the professor how the Routh criterion works, and probably that made me pass! So thank You more than a lot, Brian!
why do I pay for university teachers when I can watch this guy, and learn 3 classes worth of info in 13 min.... Thanks Brian! Great vid!
Exactly, my teacher spend 2 classes and still didn't make any sense.
Double speed and its 6 minutes hahah
pretty sure you learn Routh-Hurwitz together with root locus and other stability criteria in one single class. That said, I had an Indian lecturer whose accent was not comprehensible to me. I would love subtitles.
@Felix Carpio Of course in real cases you don't get such simple functions as polynomials :D that is just for the demonstration
Just for certificate...😥
You are the reason I'm becoming a Mechanical Engineer this Wednesday
I know it's been years, but I just came across your comment and was curious. How has it been being an engineer?
you study this as a mechanical engineer?
@@shakirobaid2895I think a lot of engineers study controls, I am in bioengineering for example
@@shakirobaid2895yes we do
@@shakirobaid2895 As a mechanical engineer, can confirm. If I choose to I can take 3 years of control courses!
I know this video is 7 years old, but I just wanted to say thank you. You're an excellent teacher.
It's 9 years old now, but I feel exactly the same way!
11 years here))@@PunmasterSTP
9:52 "Tracing number 8" !!! Now I'll never forget how to fill out a Routh array. Thanks Brian!
came down here to find this comment ^
I never comment on videos but man you're a gifted teacher, you articulated the information so well that it just clicked for me thank you!!
I had a terrific controls professor in college who taught this stuff, but I was not a very good student in this topic.
Now decades later in the latter half of my somewhat successful engineering career, I am back to muscling up on controls with this excellent series.
Thanks Brian Douglas!
No joke understood this completely in 10 seconds vs 3*45 min lectures! Legend!!!
I wish you would continue to share videos. I think
As a Control Engineer candidate in Turkey, I say, you are explaining better than you were told at the university.
So glad I have you.
Thanks! Even though I don’t post on my channel anymore I still make videos for the Matlab channel. You can find them all here: engineeringmedia.com/videos.
your explanation is top-notch!
Two lecturers * 2 hours each to explain Routh-Hurwitz Criterion in my university. summarized under 13 minutes in this video. Seriously this pattern of filling the array is much faster than memorizing the equations for each row!. I appreciate your hard work.
So much better than my lecturer's explanation, what would we do without people like you on the internet!
Gosh this is such a good explanation for Routh Array! I'm glad someone can explain control topics this good
2 weeks worth of classes in 13 min video. Thank you !
Your pattern approach is so good, I appreciate it. Memorizing equation without knowing its logic behind them is worse than memorizing the pattern without knowing the logic behind it.
One of the best videos playlists on UA-cam. Concise, precise and very clear.
Wonderful. I am teaching to University students by listening to your lectures. A must watch for everyone trying to understand Control Systems with reasoning.
Awesome Explanation in just 13 minutes, whereas people in college can't explain it in 50 minutes with this much clarity... Great Job :)
you are a best tutor and I appreciate you. As I go to my test tomorrow I will understand the test because of you.
UA-cam algorithm should recommend useful stuff like this instead of random tiktok videos. Great lecture bro. I hope i can pass the paper this time.
You saved more lives than you think with this video. 100%. Appreciate the great explanation.
Thank you for some great videos Brian. I'm a Norwegian engineering student and it has helped me a lot in understanding the Routh Array.
My university lecture on this topic was two whole hours and I got it in under 13 minutes here, thank you for your clear explanation.
you've made it 10 times more easy than how my teacher explained it! now i'm seriously mad about how much i pay in tuition fees for researches how want to teach but don't have the ability to deliver an info!

you know what man, a simple thank you could never show how much greatful i am to you, you're a hero, keep up the good job
Hi Brain, Thanks a lot it help me with my graduation.
HOLY COW!! You're the MAN! I can't thank you enough

This theory is sort of antiquated now what with Wolfram Alpha now, but without this video I would not have been able to do the damn homework. Thanks
This 12 Min probably saved me a few hours trying to understand. Thanks a lot!
can't believe this video is 12 years old . awesome, lecture!
great vid! my professors should watch you and learn something from you. hi from Turkey!
You should really be getting paid to do this, your teaching is simply phenomenal
Thank you so much! , I missed 2 weeks of univesity lectures and these videos just saved me
Two thumbs up, iv been staring at my automatic control book for an hour trying to dechipher a RH-array. Piece of cake solving it now, i subscribed!
You are really excellent at explaining this, my state university controls prof could never dream to convey the Routh, root locus or Nyquist stability methods as well as you have in your videos. Thank you very much!

Sir, this is perfect explanation. You explained 50 min class in a ten min. Thanks, hopefully you are going to keep recording.
This helped me sooo much. Thanks a lot
you are awesome! you manage to explain the example together with the theory fully in a small amount of time! that's how any youtube educator should be, make it clear and concise, thanks mate for your effort
You have spared our lives, we are eternally grateful!
You dont understand how much you made my life easy with that this is all i wanted to understand im actually writing you it while studying for my exam at this subject also i saw the video about the P , Pi , PID Controllers i found it very helpful hope ill get A , A+
U are awesome teacher, In my class madam explained this for 2 hours , Still i did not understand RH as much as listening to 13 min lecture
I've never commented on a video before, but 3 minutes in, and I realize this is great. Good job Brian!
Saved me 10 marks in my exam tonight, thanks
Thanks man! I have learned all for my last exam at University just from your channe and get 10!
Great work, you have my pledge!
This was an insanely concise and clear explanation.
Brian you are the SUPERMAN himself!!!
Great tip about the pattern and thanks for specifying what you do when you don't have a value for a power!!!
This video was very helpful for me. Was struggling with understanding my textbook examples, your video really helped me out!
I could tell you put a lot of time and effort into this video, It helps a lot.
Good Job!
these lecture are awesome, cause in classes we are only do math calculation and match the answers but here we know about the real meaning of control system n how math tool use for simplified the problems.
Thanks man! Im studying in Spain right now and as my Spanish is still not perfect these videos help alot. Keep it up.
I’m really ecstatic to watch videos and solve my assignment questions 👍🏻
I have my exam tomorrow and this video literally taught me what I needed to know so quickly. Now I went from knowing nothing to be able to gain at least a few marks.
hahaha! my day couldnt be any better without the Routh man!
Brian, your channel and the way you explain things is just excellent!
So much clarity in thought. Thanks Brian.
You nailed it sir. Keep it up. You just saved a subject in current semester
I wish I had money to pay you! Unfortunately my useless university has taken all my money and left me with nothing but confusion. You are such a champ!
That pattern for memorizing the Routh array is ingenious!
This was incredible. Your method of teaching fits brilliantly with how I learn and you were so clear and concise. Thank you!
Your videos are so great. You managed to teach subjects in a such simple yet effective way. Thank you so much!
1:55 ! That was the most beautiful e^(-at) curve EVER! SMOOTH!
Wow, finally some clear explanation on youtube
Amazing video. You could not have made it any simpler. Wish I found your channel sooner. Would have made my controls class much easier
my god u r realy amazing...i never expect the explanation like this from any tutor...u rock.....
Thanks for your videos. You are way better than my professors.
I'm glad they invented computers and matlab.
Are you a physicist? XD
This is so much much better than reading a book. Thanks
Fantastic explanation!!
And i really like how you sped up the writing so that the video moved faster.
Thanks for uploading. I've been having problems on how to get the 4th rows and so on but with the pattern introduced in the video, I now understand. Thank you. 😊😊
Cheers mate, you've explained it amazingly
great video :), watching your video just for 15 minutes can clear any sought of doubt in the topic !
Great class! You are the best teacher that I have seen!
Great video, very clear explanation. Definitely going to be watching more of your videos to get through this Linear Controls class.
Hi Brian. Your Lectures are great to fill some gaps in my study (especially when lecturer said to study Routh-Hurwitz Criterion by ourselves at home), but I have to correct you.

very interestingly explained while touching the ground basics.The entire list is awsum. More videos please!!

Great explanation. I have a control systems test coming up and this gave me the confidence I needed lol
i learn more from you than i do from my control systems professor
Awesome thank you Sir. I particularly like your tip for filling up the third and following rows of the table
Routh-Hurwitz-Man made my day!
You have no idea how much i love you
Absolutely brilliant lectures - I cannot thank you enough

Thank you so much Brian. U really know how to explain this material, even an 8th grader would b able to understand it
thank you! i was falling asleep studying this on the book and not understanding so easily! i go right to next video :)
Update: I've passed the exam of "control of energy plants" and I think it's 70% thank to this videos. In particular I managed to explain to the professor how the Routh criterion works, and probably that made me pass! So thank You more than a lot, Brian!
Just, what i was looking for, thank you !! Great video
Short and Sweet explanation. Good job!
hey brian , just watched ur lecture, very helpful, planning to go through the complete series,,thanks, great work done
Thank you very much for these videos. Really appreciate the time and effort you put into making them.
