i wanna ask you bro,how the aplication of this teory?i just know the teory

Incredible feature of sisotool that you show in the last part this video. That is a useful help for all. Thanks!

You explained how to use the root locus plots on MATLAB 100x better than all my professors. Thank you!

Keep going and don't stop uploading your videos. I am an Asst. Professor and I explain to my students after watching videos all over the internet. I think you explain very well and also you have good examples in your videos! Simple and Effective...Cheers from India

Great demonstration and walkthrough. I had not used sisotool before, what an eye opener! If you have more matlab walkthroughs like this with other tips and tricks for e.g. Bode plot that would be greatly appreciated. Keep up the good work

The Sisotool is awesome. I didn't know about it until now. What it can do is just amazing and a lot! Quite helpful

man you are extremely good at teaching & your matlab understandig is absolutely amazing ! congrats!! keep on teachig you are doing great !!

Thank you so much for your effort and dedication in making these videos! They are really awesome and helped me pretty much to understand a lot of topics of classic control. When you have time, could you make some videos talking about state space control theory? Thanks in advance! Best Regards!

I've watched a lot of your videos and learned a ton. This one was something special! Thanks a lot!

HI, I'm from Brazil, and I really appreciate your lectures! Simple awesome! Congratulations!

Excellent video, Brian! This tutorial is really effective and simple to follow! Thank you for your time.

Spotted a typo: at 9:52 in the video, the Matlab comment text says "But a downside to rlocus is that you can't see how all of the roots move at the same time, you only have control over one root. Also, you can easily see the effect of" The second "can" should be a "can't". Anyway, this is an excellent video series, Brian Douglas!

I really appreciate your videos.

Really awesome video!!!! Helped me out SO MUCH you have no idea! Thanks a lot! I hope you find great success on KZread!

I really hope you could become a lecturer in my university . I wouldnt have skipped so many classes if you were my teacher

Really good video, great help when studying root locus.

Incredible videos! Cleared out many questions I had in mind.

You are going to heaven for these videos

Thanks for uploading this one.

Very useful , your knowledge on matlab is also great. Thank you very much for your videos !

Hi Brian! First of all, thank you for helping us to understand more about this topic. I have a question. So when we use the SISO tool, and we take a look at the RootLocus, i noticed that the 'Squares' are not in the same position as the poles (for a k=1), with this transfer function you have to zoom in a lot, but i've noticed that with others transfer functions, this is more visible. So at the end using a k=1 where are our poles? Where the squares are or where the X's are?

thank you for making this video i really benefit a lot

very helpful tuto... I appreciated it enough .. only explaining the essential

This video series is exactly what I'm looking for. Btw I have a question regarding the stack TF mentioned above. I'm working with a ship-heeling-angle control system in my uni lab. The system includes two tanks located on two sides of the hull and a gear pump which pumps water back and forth into the tanks depending on the input voltage negative or positive. After conducting several experiments to determine the step responses with various step reference voltages, I figure out that the transfer functions might not look the same. I haven't done the system identification step yet, however from examining the graphs (which look like an integrating system with a time delay element) it seems like the the gain constant coef K differ from eachother. I wonder if I should work with these transfer function as a stack or you know choose one that represents the whole system? This question hasn't popped up in my head until I watched this interesting video.

This was the coolest thing i hv ever seen

@9:25 we can see that the popup shows a damping ratio term that is less than one. The question is, The damping ratio is defined only for the second order system (as stated earlier in the video). How are we applying the same concept here in the fourth order system ?

you are an awesome teacher, thanks for all your videos. can you do a video on predictive control (e.g. smith predictor)?

thanks sir your videos are really awsome.plz sir post something on block diagram questions.. it seems complicated solving them .

Super thumbs up, this was super useful. Thank you Brian.

Woa this is very cool, please make more control system MATLAB video.

Thank you for your efforts, great vids Keep up the awesome work!

Simply impeccable.

Your videos is more than helpful ..Thanks Continue... :)

great explaination of matlab for root locus

Awesome videos ..Loved it .... Can you make video with some real life problem and solving it using Matlab ? (Tools used can be root locus , Bode Plot ,Nyquist PLot ,Lead and Lag Compensator ,PID Tune ) That would be an amazing experience to learn under you.Thank you:)

Great lessons. Do you have any plans in presenting an equivalent analysis in the Z domain?

🔥🔥🔥 so cool, u make this course so interesting when compared to my prof

You are awesome! Thank you for doing this!

awesome, can you help with how can i introduce any transfer function, i mean i want to make a programm which could ask for any transfer function and it could plot rlocus method

has the sisotool changed because mine looks completely different and I can't do this stuff anymore?

you are legend man wish to u all the best and thank u so much

lo amo señor , muchas gracias

The videos are very helpful in order to understand the deep concepts behind the Root Locus technique. But I do have a pretty confusing question, actually two questions. I have understood all the concepts but this fundamental one is confusing me a bit. My first question is that we use Root Locus in order to analyze our closed loop system like how the poles of our closed loop system move as we vary ''k". So then why do we plot the root locus of GH only why not 1 + GH? My second question is pretty related to the first one. In one of your video, you said that our closed loop poles travel from the open loop poles to the open loop zeros. What does that mean?

helped a lot. many thanks

Brian Brilliant !! Another great video. Could you pls talk about the impact of the "pure delay" in the stability of the system.

YOU ARE THE SYSTEM CONTROL GOD!!

Thank you so much...This video very useful.

Don't stop making videos like this ...

Would you recommend MATHEMATICA and SYSTEMMODELER for Control System Analysis ? Or MATLAB would be a better choice for this purpose ?

terrific! i would like to know something maybe trivial when you design a controller, you are adding notch, zeros...in order to meet the requirements. but can you add whatever you want?i mean what is the meaning in term of hardware, what is the cost of this?thank you a lot

@BrianBDouglas

Tony Sznabel Not trivial at all! When you're working in the S-domain and just adding poles and zeros it's easy to lose track of what that actually means. Whatever controller you design you have to build - and more complicated designs require more components. But beyond that, you might actually build a controller that attempts to drive your actuators faster than they can be driven and that's not going to work. For example, I can design something that controls a motor so that it has a step response rise time of 1 millisecond and my simulation will say no problem. But if the system can't source that much current, or that high of voltage (or if the change in current doesn't occur fast enough) then the motor actually won't accelerate as fast as my controller is driving it. The best way to learn all of this is to take on a small project at home and see how your real hardware behaves compared to the ideal model you've assumed. Hope that helped a bit.

im using matlab 2020a windows 10, only location, damping and natural f shown at the bottom, any idea how can i get the gain value?

Great videos, could you please share a video on Digital PI controller for a motor current loop.

Thanks man, this video very useful.

I have a control system where there is a disturbance that only comes into effect after 100 seconds. I am wondering how I incorperate this into the transfer function of the system? Any help would be greatly appreciated

Thank You very much Your videos are very good

This was really good!

Why isn't the transfer function at the beginning of the problem in the form of Gcl = (kGH/(1+kGH) ?

Most seems to work in MATLAB 2024 as well. Great video.

How can I draw root locus for system with PR controler [1+Ki*s/(s^2+50^2)] and the object is G = (s+1)/(s^3+10s+15) when Ki change

NICE!!! Thank you! Great video.

Great tutorial bro

This is really fantastic because you re fantastic

very helpful, thank you

You are the best man!

My muscle "Gains" have been dropping recently. Should i use a lead or lag compensator?

Dude thanks a million.

did a great job

how to get k value in transfer function brotha?

how did u get k g(s) h(s)....at the beginning of the vid

Very useful!

This video is better than the new Star Wars.

you r really good, thanks a lot

how can we write constant with gain in matlab

I dont know about you guys but when I open control system designer I only get one window the design window and I can't find a manager window anywhere.

Amazing thank u a lot. .

nice work....... u r great bro

I love this video

what version of matlab do you use?

Which software is used for writing?

fantastic! thanks!

good job

Thank you sir.

Question: Write a code to simulate the root locus for any simple transfer function G(S) H(S) and verify the solution by sketching the root locus for the same transfer function choosen.

Why, if the gain increases as you move through the root locus, is the step response stabilizing always at 1? Shouldn't the unitary step be multiplied by the gain in question?

@tutimoyano

Because that step response is for the closed loop system. The plot of "step(GH*k)" and "step(feedback(GH*k,1))" are different.
