Amazing, this is what we should learn in unis

[@rabeash711]

Your channel is amazing too 😍

[@simonriley7750]

Too bad we don't. Almost getting master's degree in control engineering and all we have done practically are 3 lab exercises with total lab time of 10h. put into perspective, it's 2 days worth of theory classes (3% of the whole semester)...

[@qdav5]

Agree. Control classes almost always start with the assumption that your plant model is linear, time-invariant and known. And even more so with advanced classes. A lot of professors seem to get side-tracked with all of the elegant mathematics and neglect many of the practical aspects of control system design.

[@heithemboufrioua7237]

mr walid your channel helps me a lot thank you so much

[@nrdesign1991]

@@qdav5 Exactly this! But this isnt the real world, only some abstracts to get you started - The same thing was trigonometry in school, completely abstract and seemingly impractical. Putting it into practice, and it starts making sense.

[@AlexTaradov]

Please do more of practical things. The stuff at the beginning is exactly how I felt out of the Uni.

[@itsmethemario8846]

As an EE master student focus in control, this video is literally god sent. It makes me have more confidents in myself, not only because i understood everything you say but also because my knowledges from Uni CAN be applied to solve real world problems. Thank you very much.

[@apm]

Brian, thanks for another great video and for highlighting the Temperature Control Lab. It is great to see how control system theory works with real data. You've done a great job fitting an overview of controller development into one video.

[@WalidIssa]

Great work to you as well

[@tuloca011]

This is pure gold

[@emiliotanowe4323]

Great video, Brian! I used to watch your videos while I was a Bachelor's student, and I still watch them now as a PhD student (in Control Engineering)!

[@vmxavier7]

After all the control classes I've attended to....your videos still amaze me. What a great way to teach!

[@Tuong11a]

Thanks. I studied Automatic control at University, but pure of theory and math. Your video opens my eyes :)

[@Jacob011]

This is leaps and bounds better than any paid course I've ever seen!

[@ddskimmer]

Brian thank you so much for your generosity! I'm 58 years old and always loved tinkering as a kid but, my family situation growing up was not conducive to supporting my desires. I became a sales person, then a technical sales person and had to retire early do to my health. I thank you for being such a good teacher. Now I have some time in my hands, and hope...God Willing to be able to put it into building me some things from scratch. I hope and pray to build an EV, ATV...machine. I have ideas that I'd like to pursue and your videos are letting me know whether or not they are realistic. I feel great to an extent by what you said about just learning the background of the processes "the philosophy" of it is what comes to mind now, and that indeed we are working with existing components / systems...that have done all the math work already. I would be lost without your in put and I do need to learn my electronics and math all over again. I know, I have a long way to go. Thanks to you I am becoming able to relate with the "WHY" aspect of things. My math teacher when I was in High School tried to explain the "Why?" purpose of the Algebra but I never recalled him succeeding with me in this area. Then again we didn't have MatLab, and such richness of electronics to workout these algorithms. The concepts and how you explain them give universal understanding for correct EV applications and anything to do with EV or Hybrid or anything one needs to automate using control systems. I have subscribed and will share it on facebook...with the hopes your coverage will increase and you get many more subscribers. God Bless and all the very Best! Have you tried publishing some of your courses in Udemy (dot com) ?

[@nathancleavinger6975]

Thank you so much, Brian! As a senior getting ready to graduate (and struggling in my controls class), I really appreciated the way you bridged academic knowledge and real world experience.

[@sunkist848]

Amazing video! Literally shortcuts years of learning that a student usually would need to actually understand how to apply controls principals in a real life scenario. I wish this is how they taught controls in universities!

[@gabrielanghinoni4623]

Probably the best video about Control theory in the whole internet. Amazing work, one day I will give it back too. Thank you!

[@Bear_wonder]

I liked it. The beginning aspect of the video explaining the setup was fantastic.

[@Darkbob-ew1lk]

This video is pure gold, I spent 2 years getting my masters degree in non linear control and never had seen such a clear and well explained implementation example.

[@devinmckee5463]

First of all, WOW, this is such an incrediblle video! You have such an incredible talent for teaching! Second of all, I am on my senior year for a BS in ME. I have been putting SO much time and effort into trying to understand all of the subtle, complex, and outrageous concepts involved in my clasess up to this point. However, there has always been the ever looping thought to myself, why put in SO much effort? What is the point of truely understnad every distinct concept of Thermo, heat transfer, programing, dynamics, physics, circuits...the list goes on... What if this is all a waste of time, and I will never need to know these subtlties in my future, real world engineering profession. But this video does a fantastic job of detailing that proves to myself that everything can tie back together if I know how to connect the pieces when it comes to reality situations. From what I've learned in my classes is that everything comes back, don't cheat yourself cause it'll come back again. Thank you for being the post-school engineer that takes the time to showing us students why everything can potentially matter. You showed me my hard earned effort can and will make me the best engineer I can be.

[@inigomeniego4906]

I have so many tabs with your videos that I feel I will never end them. Thank you!

[@sixstation6480]

Trying to design a control system for a model greenhouse...heater, vents, fan...not a mechanical engineer, rather an electronics tech...so a video like this is great to understand the issues involved, and the underlying principles and fundamentals. Thanks

[@luisgerardorodriguez7964]

To me this videos are AMAZING, I am an Electronic Engineer and I have no doubt this has been the best video related to control systems

[@tolgaHankq]

I'm at my freshman year as a control and automation engineer and this video was so helpful to foresee what I will do in the real world with all those theorems. Please keep making like this kind of videos. Thank you so much!

[@themerpheus]

This is the best content I have ever seen in youtube for the control theory's sample applications. Keep forward with practical applications sir. Thank you.

[@carlosrodriguez7120]

I do agree with Walid Issa, schools have to spend more time on practical approaches to control design rather than spending the whole time on the theory. Your video was amazing. Please, keep it up.

[@epeglab1o1]

This is brilliant. Would love to see more!

[@nirbhaythacker6662]

I'm at school and don't have enough time to watch the video, but I'm happy that you're back to posting great educational content.

[@nunziobarone5102]

Thank You for this video, i'm a control engineering student and this i what i need, a practical example of what i study at university

[@OrangeDurito]

This is what I want to learn. It's very hard to tie the theory with practice when all you are fed is the mathematics and simulation at best. To see the implementation on an actual hardware and you reasoning through the problems made the theory much more clear. Thank you so much! Your videos have helped me a ton.

[@fikunmiajayi]

Hey Brian, you're a legend. I think you're doing the most for Control Students all over the world, your videos often address all the issues I have in my head, they answer questions that my lecturers often don't care about. I loved the one on Laplace and this has quickly become my second favorite. Words cannot express how much I think of you but thanks man!

[@jdiogoforte]

I find your videos quite inspiring! I really liked this one, its nice to show, from time to time, how things are done "in real life" to add some spice to the theory.

[@huanmin955]

Your video has been incredibly helpful for engineering students in understanding control theory and its real-life applications. Applying control theory to real-world scenarios is a key focus of my research. Your video has inspired me and provided valuable guidance for this goal.

[@anonymousowl5240]

Really appreciate the video! I have my first interview to be a controls engineer coming in about an hour!

How'd you go?

[@YashRaj-ix1dp]

I am currently struggling in tunning PID for my drone. Now I feel I know how to approach like an engineer. Kudos for this video. I have started liking control engineering.

[@RobSummers993]

GREAT video! It really helps to see a real-world application of this subject. This has really helped to solidify my foundation. Thanks again!

[@ВениславЗдравков]

All your videos are great, but I think this is special because after two semesters of control theory I could not answer the question of what exactly I am learning? Some equations? Math? You give me the answer to this question and give a sense to me and motivation! Big thanks!

[@puneetpanwar2907]

Brian, first of all thank you for making such an informative video; which I found is a perfect blend of theory and practical aspect for building control systems. I would suggest you to continue this series with implementing advanced controllers(like MPC, Optimal and robust controllers). It would be great of you to explain the orange box to beginners so they may get an overview of communication between computer and arduino board. In the end, a big thumbs up for your work !

[@nathikdiaries]

Hey Brian, I am one of your Patreons. I deeply agree with the other people who have commented on these videos. I have my masters in electrical engineering and I have learn about the theory repeatedly but the only thing I know to do in practice is tuning PID controllers. For the first time, I understand the significance of the step response and I can't thank you enough for that. Please please please post more videos of practical, even if there isn't hardware, just working within a simulator is great! Some of the stuff I would love to see are state space equations in practice.

[@xToTaLBoReDoMx]

Please do more! I just finished an introductory controls class and our final lab was pretty much exactly what you did here. Your videos were a huge help btw, but what are some more advanced control strategies outside of the standard PID, lead/lag/notch, feedforward, etc? I'm hooked on controls now and I'd love to see some videos of more advanced controllers and where they're used.

[@Special1122]

how about going into state space model? one of the methods I heard about is full state feedback

[@anglebertmasunda6132]

Thank you Brian. This really helped in getting an overview of all the critical steps involved.

[@volkanyildirim48]

it is a blessing to see all the concepts taught at school to put in action. it is even better to see while still in school :)

[@capistor1]

thank you so much for showing me that designing a product doesn't necessarily have to be a trial and error process and that parameters can be simulated in such a manner. i had no idea!

[@electron_]

Amazing video, you walked thru my college knowledge and brought me back where I am working now as onboard ETO, A lot completely I meet here starting from basic PID up to Calman filter. The best engineers always have a strong mathematical knowledge, I can see it now after 11 years onboard.

[@venal7]

This is how everyone should teach. Love it

[@AthanCondax]

Hey Brian, I've been watching your videos (and supporting your Patreon) for a while now. This is truly excellent. Your videos have already helped to bridge the gap between theoretical and practical applications of control theory and this video took it to another level. Based on the feedback in this comments section, I definitely think that doing things like this are what people truly want to see. I'd love to see more.

[@humzahalkindi]

I found this video very helpful. It gives me a big picture overview of the entire process.

[@harrypehkonen]

Ever since I learned about PID controllers, I felt that something was missing -- for example, the delay. I think you explained very nicely how the "missing parts" are actually just part of the search for correct parameters! Great explanation!

[@Marchel0522]

I really love your videos, all of them, doesn't matter if it's theory or practical applications, they do help me to see the connections between paper and the real world. When you talked about how it was for you right after you graduated from university with that mindset "there has to be an optimal solution", it really resonated with me. Hope you're doing well man, your work has a good cause. Greetings from Mexico!

[@tayyabashfaq3939]

This type of content needed to go further a sort of a playlist. I could watch all day.

[@JoseLuisSarmiento]

This should be the first class in any Control Engineering course at universities. Really good!

[@nismoskys]

This was an incredible overview. Loved how you build it up starting with an open loop, adding the closed loop, and showed the graph giving a real sense of the value of characterizing the system, and showing how feed forward and model predictive control can be used too (many questions on these). Superb content. Thank you!

0:00 to 2:39 ... Best statement of experience stated in a concise manner. Ever. Still, the best lecturer for control system design. Ever.

Great video (even considering your super-high standards). You said it'd be a marathon... but the pacing was great, and you had me on the edge of my seat the whole time! I'd love to see more videos in this series demonstrating different controller design techniques with actual hardware. Having a real system responding to the controller makes it so easy to visualize and contextualize everything. Thanks for all your hard work.

[@rileyellis1623]

I came here after watching the video from your latest LinkedIn post where you summarized control theory. I really want to learn more about applying control theory as well as utilizing tools like Matlab and Simulink. I don't have any experience with system identification, so it was neat to see. Hopefully you have content on that!

Fantastic, I myself have used this device for learning control theory in the context of chemical processes at the undergraduate level. It is refreshing to see the benefit of using this device from another perspective, and I learned a couple things I didn't know about the overall control system design process. Thanks for this excellent lecture!

This is phenomenal, thank you! KZbin is awash in content created from limited understanding in the workings of whatever systems they are attempting to instruct on. This video serves as a first class example of the much needed filling that huge void; Knowledge in the field, examples, real world application, use of various tools, and information clarity. Thank you for this. I highly anticipate your content.

[@ifindev]

OOO MY GOD!!!! This is it!!! This is what everyone at the Unis should teach us about. A theory is great, but without practical knowledge, every theory I learned seems like a waste when I have to design a control system in a real situation. Thank you so much :). I'll make my project myself after this. I never knew that you can use Matlab and python that way to figure out the mathematical function of a system. I learned something new today. Once again, thank you so much, Brian. Please do make more videos of this practical example. :D

really love you sir. Your videos is more usefull and time-saving than a bunch of classes in my university

[@erlfram]

I think you should have tested your final controller in the end with disturbances like the hairdryer. To see the final design working in action is very rewarding, especially if we can see that the system now performs way better than the earlier stages of the controller :)

Great video Brian! I think we all should learn a lot more concerning more practical and useful approach to engineering problems. Not only academic equations and theoretical graphs. I wish you did more videos like this - with actual examples of specific control systems. I graduated from Aerospace Engineering and your videos helped me a lot in understanding basics of control systems and then auto-flight systems.

[@giorsoros1135]

Great Video !! I did something like this before but with self built system using power resistor (as heater), mosfet (as amplifier), tmp36 (temp sensor) and arduino as controller. I stopped until making PI controller without mathematical model. I was a successful one though. Now I'm working on figuring out whether there are better ammplifiers and how to generate the mathematical model. This video show another way to do it with matlab and phython (I did mine one with arduino IDE). Thanks for the knowledge !!
