PID Control - A brief introduction

[@fredmtucker]

Videos like this are good examples of good people using the internet for for what it was intended for - the relaying of useful information people can use. Brian Douglas - and those like him who teach the rest of us - are simply awesome.

[@BrodaQD]

Good video and the followup video was even better. Subscribed to the guy's channel immediately.

[@garyha2650]

PID: "A proportional-integral-derivative controller is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control." What's the simplest or most easily understood example?

Uploaded on 2013. No fancy graphics, good pace of teaching. A timeless video.

You sir, are part of what makes me glad I'm studying to be an engineer.

[@chrisw.9845]

speaking in technical terms and basic terms, your also agreat engineer

[@jordyborquez6852]

Hey Brian.. 10 years later and here I am watching your videos! 10 years ago I would have never thought I’d end up in this Industry…

[@hoofheartedicemelted296]

If I'm honest my age means we didn't have this technology available when I was a lad, but I watched the video 3 times and it actually began to make sense. You're a very good teacher.

[@jasperzoey1912]

With the help of..DR RORPOPOR HERBAL ON KZbin i have been cured totally from PID....

[@chichi7391]

I'm an ME and took automatic controls a few years ago and your videos are great for review! Thanks for taking the time to make them!

[@davidchuong714]

This is the single best explanation of PID control I have ever come across since I was first exposed to it 4 years ago. Often times as engineers, we get math equations thrown at us, but the intuition behind that math is lacking. This video is perfect for developing an intuitive understanding of those concepts.

[@builtdifferent276]

Very cool , thank you! I've just starting electrical engineering and now I need to ask my robot to move on a straight line , which is why I need to know more about PID. Again , very good video!

[@bug13wu]

best ever, if all tutors teach like this, there will be a lot of good engineers, and the world will be a lot better place

[@Fsifab]

Excellent work! I'm so glad I found your channel. I wish I had access to this 10 years ago when studying control systems in college. Your explanations have given me a whole new interest in getting back to these topics. Thanks and please keep posting you videos!

[@hackerofawesomeness]

I look away for one second and Wall-E is there. The drawing is on point, the viewer doesn't have to wait for you to draw so you're always engaged, and the lecture is really good.

pizz delivery is amazing. i second that

[@abhinavsixfaces]

Just draws wall-e casually while explaining control systems. i love these videos.

[@TruuuthFinder]

I studied engineering. This was the one subject I never really understood. This video would have been helpful back then! Excellent and simple!

[@Eli-yu1by]

Man, this video is amazing. Succinctly said everything I was taught over 2 to 3 50-minute lectures lol.

[@callmedeno]

Absolutely stunning how easy you made it to understand in such a short time! subbed

[@rafhanah92]

I just want you to know, this basic but wonderful explanation is hugely contributing to the beginning of a new and powerful inventions for the world in the future!

[@Themachinewon]

Thank God for guys like you, who are out here !

[@controllaw3665]

We love this channel and it was one of the reasons to start our own. We are a very new channel and will bring content on control theory, linear systems and systems identification. Keep inspiring people, thank you very much!

[@aryanmishra5591]

Wow the best intuitive video there is on the PID controllers out there. Either you have an exceptional ability to simplify stuff or others don't know how to explain this simply enough. Thank you so much for this.

[@aaronbornmann9835]

You a hero, saving a South African University student right here. Thank you Brian!

[@elizabethmstudios8692]

I used Brian’s tutorials for my Control Systems module at Tuks. Offered by Prof. Ian

[@hosseinazimimojtahedi1442]

Hi Brian, You are doing a great job, easy to explain and understand for everyone is interested in control system. I suggest beside the title on each video you make, put a series number to catch up continuously for watching. Great job, thanks.

[@mernaayman7784]

Seriously thank you so much Brian 🙏✌ I am studying electromechanical engineering and whenever I need to understand anything related to control I open your channel and you have all topics covered. You are a great teacher.

[@AlphaChaka]

I just passed, and it was due to your videos. Thank you very much. ;) You're help is going all the way to Portugal ! And I'm not the only one, I guarantee it

[@JasonBurtonWellness]

Brian, your videos are great. I'm surprised that you don't have more subscribers. I find these lectures extremely informative and easy to follow. Thank you for taking the time to make these videos available. This is how we advance the human race.

Yup AWESOME is the operative word here. Keep making these. You have a gift. I wish I had you for a teacher.

[@yuvarajn.g5915]

Excellent explanation.. you made it easy to under stand. I have completed my Electrical Engineering and your video is really useful.

[@ecotive]

Dear Brian, I hope you and your significant ones are healthy during the current Covid outbreak. Thank you for your efforts on KZbin, I really enjoyed the content and am still following. Due to the way you explain the control theory, I wanted to ask if you may do something about the Integral Sliding Mode control structure. It will be really helpful. Thank you very much, and I wish you a great day.

[@TaterBot1000]

Finally, a clear understanding of PID controllers! You have saved my brain and my grade. lol

Hey brian first of all thanks to you for such a great video series on control system. I request you to put videos on ipid(intelligent PID) as well as ADRC(Automatic distortion rejection control).

[@yash1152]

> _"videos on ipid(intelligent PID) as well as ADRC(Automatic distortion rejection control)"_ can u share briefly what these are?

7:07....is the reason why many people do not do good in engineering studies...especially in India!!!

[@Nico35100]

in italy too, man! ahah too much theory and few exaples! One of my profs,2 years ago,told us(poor fishermans) that chemical engineering in india and in italy is studied with more theory than in any nations in the world, should be true?! anyway great video!!!! :)

[@HrushikeshNaik1650763n73]

Great vid and really helpful! Better than my lecturer for sure

[@Scolastice]

Great lecture! I have two questions concerning the paths (4:09) thought: 1. Why is it only k_p and not k_p*s on the proportional path? 2. How comes you multiply the k_i with 1/s and not f.ex. s on the integral path?

[@HrushikeshNaik1650763n73]

PaJo GaMo 1.Kp. is a linear function not a exponential function. So we do not multiply anything to it 2. Ki times integral of e^st is simply Ki * 1/s 3. Kd times derivative of e^st is simply Kd * s

[@Mr07031944]

It is great to get the fundamentals so clear. Is it possible to save the videos for study and refreshing later also.

You're probably just joking, but here's the video: kzbin.info/www/bejne/jpekpWmeg7trjq8 It's not in the box because KZbin recently ended support for annotations, so tons of old videos are broken like this

I don't even know if I'll have a class about controls but this video was interesting.

[@yjy3058]

Thank you for your video. I actually have questions about PID output. In your video at 2:40, what is the unit of PID output?? How can I make the output from PID connected to the output even though the unit is different?? For example, we are going to do PID control for valve at the outlet of the tank with level transmitter installed on the tank. We measure level and make level error with our desired set point. We put the level error in the PID function and give the PID output to the valve. Here is my question.. The error is from level and PID function is going to work to remove the level error. BUt HOW CAN WE MAKE CONNECTION BETWEEN PID OUTPUT AND VALVE POSITION CONTROL????? ACTUALLY LEVEL HAS NOTHING WITH VALVE POSITION WHEN CONSIDERING UNIT AND RANGE. The unit is even different. This makes me crazy and I cannot find any information...can you help me?? Can I think that; PID does not care what the valve is. It only gives the pID output to the valve, whatever, etc. depending on error. AS PID will give the output to SOMETHING, there will be some change in the output and we will check it again with closed loop control. If the output is closed to our requested value, valve will not move too much as like before. Is this correct?
