That’s usually the case if you heard of something before and someone comes by and explains in a little different way. Everything you heard in class just seems to finally connect. If you never heard of something before that video might be helpful but still leaves you with tons of questions for the actual details
This is the greatest simple explanation of PID controllers that I have ever watched. It helps you to understand why there is a proportional and integral and derivative controllers. Thank you so much for this video .
Can anyone please explain, why after controlling it became walking speed? At first it was error between reference point and altitude. Then why it became speed after using PID controller. Please explain
@@nadiaakter9351 The controller takes as input the "error signal" (which is the distance between the desired altitude and the actual drone altitude) and outputs the input to the drone (the propellers' speed). You need to think about what are the actuators of your plant and what can you control. Your plant (Drone) has 4 independent actuators (4 propellers) for which you can control their rpm/speed (via providing more current). So, your controller takes as input the difference in altitude ("error") and and tells each propeller how fast to spin in order to reach the desired altitude. Hope that helps.
I see a lot of people in the comments saying that this was more useful than all the lectures at school. My lecturer was smart. He gave us this video at the first lecture of the semester.
I spent a shit load of time studying control systems in college, always learning something but never really understanding what the actual f**k it's on about. If only someone made a video like this at the beginning, it would have been a lot different. TY for this very good explanation.
I did master's in control systems, I fucked up 2 years. Better I would have learnt by self and online material 😂😂😂😂. So much pain in my heart 💔 😭😭 after doing time pass for 2 years
@@ericgilkey3549 Problem is, we get really good at the "boring" part with zero understanding or ability to apply the knowledge at all. We're karateka's who've never sparred.
I’ve got a M.Sc. in control theory. They don’t teach the practical part of it enough, particularly in undergraduate engineering. At least nowadays we can run simulations like with simulink and get a good idea of how to tune up a controller.
I got B in my control systems course , my teacher hardly ever bought up any real life example , and I was just in it for passing grade , thank you for making this interesting again.
Hi I've been through a few vids about this and this is the best explanation yet. In fact after watching the others I understood what it did but not how. Now I know. Thanks.
I got my bachelor degree for almost 4 years still blurred but just only spend time within 11.41 minutes really made me truly understand about PID system. Whats a great such a explaination!Many thanks
I am studying Electrical Engineering and after already passing Control Theory this is by far the best explanation to introduce this subject! Great Job!
Brian...I preach the Bible. I learned a little while ago...about infinity when looking at the exact point in the sine wave diagrams...that the one instance in a particular slice of time...the single point...is infinite...and it is a straight line...no matter what the shape is at any point in time it is a straight line. Newton was a minister of the Word of God...in case you didn't know this...he was a preacher as well. Now in the Bible we have John 1 verse 1; In the beginning was the Word and the Word was God; 2 The same was in the beginning with God. In Ezekiel we find something interesting...which blew my mind when I heard the explanation of the single point on the sine wave being straight line. Straight. This passage describes God as not only straight in all directions but where ever he moves...the universe gives way for Him to pass! He is Straight. Here: Ezekiel 1 4 And I looked, and, behold, a whirlwind came out of the north, a great cloud, and a fire infolding itself, and a brightness was about it, and out of the midst thereof as the colour of amber, out of the midst of the fire. 5 Also out of the midst thereof came the likeness of four living creatures. And this was their appearance; they had the likeness of a man. 6 And every one had four faces, and every one had four wings. 7 And their feet were straight feet; and the sole of their feet was like the sole of a calf’s foot: and they sparkled like the colour of burnished brass. 8 And they had the hands of a man under their wings on their four sides; and they four had their faces and their wings. 9 Their wings were joined one to another; they turned not when they went; they went every one straight forward. 10 As for the likeness of their faces, they four had the face of a man, and the face of a lion, on the right side: and they four had the face of an ox on the left side; they four also had the face of an eagle. 11 Thus were their faces: and their wings were stretched upward; two wings of every one were joined one to another, and two covered their bodies. 12 And they went every one straight forward: whither the spirit was to go, they went; and they turned not when they went. When Jesus Christ walked on earth, all the miracles He performed and all the marvels He did were all against the laws of nature...the walking on water, raising the dead, healing the sick...all against the laws of nature...for He was God Incarnate...is what the Bible teaches us...perfection. So, it is when you do an inverse operation in calculus...God's ways are opposite of ours...inverse of our wisdom, understanding and logic...for it is by Faith...His Faith where we live. God Bless and thank you.
i wanna say If you want to be a control engineer and if you don't follow Brian's Channel, i bet you can only reach half the way to your dreams. You are Great Brian.
This is exactly what needs to be taught at the beginning of a control engineering course, not the endless "s formulas" that make students clueless about its real life meaning
The knowledge you have gained lets you explain this concept so easily rather than half minded UA-camrs how can't explain why PID is really used. This video is a great example of Feynman's technique.
This is great Brian, congratulations on teaming up with MATLAB...I'll continue to support your Patreon work, and this is a really nice addition to that body of work. Thanks again.
Finally, someone explaining the theory behind PIDs and not just telling me a (seemingly) arbitrary set of steps to make my quad fly “good enough”. Very well explained, thanks for making this!
"This PID controller video couldn't have come at a better time for me! I'm currently building a drone, and I was struggling to find clear guidance on how to implement altitude changes effectively. Surprisingly, there was little information on UA-cam until I stumbled upon this gem.

Thanks a ton for making such an informative and easy-to-understand video! 🚁👏"
I swear I was understanding nothing to PID controllers in class, this video did such an excellent work at simplifying just for us to get the concept and understand the point of the PID This is absolutely amazing, I feel so better tnow
At the end of the video, you say thank you, thank you mainly for putting our 1-semester course into 12 minutes with such a simple explanation. As Einstein said, If you can't explain it simply, you don't understand the subject. I can set everything up simpler now. I am grateful to you.Yours truly.
Salute to you! After spending very long time in trying to figure out the topic did so in astonishingly a short time! You are indeed a good teacher! From India.....Love you!
I've watched many videos from Brian Douglas at his own channel quite a few years ago and this seems to be an ultimate, distilled version of many videos and it is extremely didactic and clean. Congrats!
Thank you so much for your work!! I am going to graduate as an electronic engineer this year and this is the first time I understand how a PID really works! Saludos desde España!
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!
Engineering education would be greatly improved if courses started with presentations like this. Context makes understanding subsequent details so much easier!
Just a minor error in your drone example. The PID output is propeller speed and the error is the difference between desired altitude and actual altitude. Very nice video.

Explaination is beyond excellent. I wrote it down all every word u say and all that. It take 14 pages and 2&half hour. 👏👏👏🙌🔥🔥
Explaining something very good it means you know it 100x times even better. Lots of clueless teachers are in universities these days
Glad to see this video before my exam tomorrow. I've never seen such a useful video. Thank you Brian!
Brian!! Honestly, I was thinking of dropping out of my Controls course but because of you I'm staying. Keep it up
One if the most informative videos on this matter in all youtube
