in 1 minute and 28 seconds, without saying a single word, you have explained how PID tuning works better than any other article or video I have ever seen

Imagine watching this without knowing nothing at all about Control theory

I have no idea what this is and what's going on. But this is still more important than my spanish homework

I suddenly understand how to tune my quad, thanks for the video very informative

If you already have a general grasp of what a PID Loop does, this is actually really straightforward and practical information for understanding how it affects real objects. Thanks for the demonstration.

For those who studied control systems/theory/engineering and still didn't understand P : Proportional gain (makes system faster, improving response) D : Derivative gain (improves transient response, i.e. from before moving to settling) I : Integral gain (improves steady state error, i.e. closer to where it should settle) 0:17 : Unit step input Very bad transient (wiggles) and steady state response 0:23 : Proportional gain increased System response is now faster 0:31 [PD]: Derivative gain increased Transient part improved (no wiggles) 0:52 Integral gain reduces steady state error, Notice the error it gets in steady state with decrease in integrak gain

The missile knows where is it by knowing where it isn't...

this video illustrates one of the most important points about learning -- quick iteration is key! Imagine learning this by watching water levels endlessly oscillate around the setpoint at a frequency of 0.05 hz...

1:29 seconds with zero words explained PID better than three lectures with 120+ slides

I just love how without words, all of us just got intuitive understanding of what PID does and how it "feels" what parameters do.

My teacher has been explaining this for 2 years now and 1 hour before my exam I find this video. You saved my semester man. Thanks

For those not in the know, PID stands for proportional, integral, derivative control. I’ll break it down: P: if you’re not where you want to be, get there. I: if you haven’t been where you want to be for a long time, get there faster D: if you’re getting close to where you want to be, slow down. Motors, in general, don’t start or stop on a dime. So it’s easy to overshoot, undershoot, whatever. PID allows you to dial in those three concepts with numbers. P.s. read the video description carefully

While playing with implementing PID in Unity3D I found that: P: is just a vector pointing towards goal, that can be used as a force vector. The farther you are the bigger magnitude and bigger force to apply. D: is predicting future by analyzing last and current P values. It acts like a break since it's vector value is pointed in (almost) opposite direction. D stabilizes motion and prevents overshooting. I: this is harder to explain, because integral value not only don't help, but makes things harder to stabilize. It's main goal is to counter external forces, like for example wind or gravity. For example if you have Quadcopter that has GPS and can fly to a given position. Using only P and D won't allow to reach desired height, because gravity will become equal to proportional force so quadcopter will stabilize at some lower height and with stabilized position D will be equal zero (value - value = 0). In such case Integral becomes important since it is basically a sum of all previous P values multiplied by time intervals. So when a PID devices reaches a stable position far from goal integral value will build up which will increase PID value to reach goal despite all external forces. Integral makes PID immune to wind, gravity, ocean waves and other external influence. Sum of P and D will approach zero when approaching goal, but I value can be anything. It should become zero exactly in goal overtime, but in real life scenario external forces will prevent to reach exact goal position and even an epsilon difference is enough to keep integral value at any level. At such stable state integral value will become opposite to external influence like gravity.

Entire day I have been reading papers and watching various videos and this simple video with no words explained it much better than all of them, amazingly simple! Thank you!

I spend many hours by learning PID. My professors couldn’t explain this in simple words. They used „science terms” which bored me af xD. Finally, I didin’t know how exacly it works... Until today. I swear, 1 minute of this video is more brighter, then hours of their talking in class xD

PID is one of most powerful and versatile algorithms out there, whether for having a robot track an object, or a person drive a car. There are so many examples in both technology and nature that makes this tool for reaching and maintaining a goal state so useful (in the human body, this is called homeostasis and what provides us with our sense of balance and being able to walk upright, or to maintain a constant body temperature.

literally did an entire class on control systems and PID control, pretty sure I learned more from this 1.5 minute video and description than I did a whole semester, thanks university.

Yep. Now I’m certain that I’ve watched too many useless machine videos to get this treasure in my recommendation.

It is very strange. I never thought that a short video without words would be so informative.

Not a single word. And now I know what PID is. You sir, deserve a like.

I’ve been trying to visualize what each does for months now and this video has literally made it all click. This is perfect.

Very simple video with no words but it really says a lot, thank you for this great visual explanation.

I woke up at 5 AM and found this video. I had 0 clue what I was watching but I watched it twice. I then Googled PID. Side note, inflamed pelvic disease, is a thing, who knew? After doing a bit of reading, I now understand what I watched. Pretty cool.

Thank you so much that was the most easiest way I have seen to understand PID tuning. Out of all the mumbo-jumbo that's out there this really help show people like me that have to see it to understand it. So thank you I will say this video and reference it anytime I'm tuning. That was great thinking.

Tip: best way to tune PID is to tune P to get it mostly there, then D to smooth it, then I

We were made to do this with a heat source and a temps sensor. -it took hours making changes to the parameters and plotting. This is a nice visual introduction - well made.

Explanation for those who have questions: The upper right hand switch controls the system power supply. The lower left side switch sets all the potentiometers to zero (down) or enabled (up). The upper pulley and pointer are mounted on a motor. The motor drives the lower pulley through the drive belt, which turns the position potentiometer as the system measured variable. The left side potentiometer is the system position setpoint. The pointer, and the position potentiometer attempt to follow the position of the set point potentiometer. When the enable switch is down, the set point, position, and PID potentiometers are all set to zero. The effects of P, I and D can be observed by adjusting their respective control potentiometers. Most feedback control systems are tuned for stability using different settings of P, P and I, P and D, or all three. There are also I controllers but are not very common.

What a great educational tool! Visual aids really help solidify theory in a way that is much more intuitive than crunching numbers. Great demo!

the best example

I understand PID control loops. I've programmed servos, analog as well as digital parameters in a servo controller, and while this video demonstrates the concepts some explanation of what is being demonstrated would have greatly improved the educational value.

This video explained PID better than 3 years of school and 5 years apprenticeship as an industrial electrician. Well done.

I sir salute you. Nothing else has ever made this much sense. Thank you so much for this beautiful demonstration

Perfect example. Thank you!

When I studied control systems last year, I found it hard to visualize what the individual gains of the PID controller actually did. This simple 1 minute video was more helpful than any of the plots in MATLAB I made to visualize how a PID controller actually works! Too bad I didn't see this last year haha. I miss the course actually, it was really fun and we got to regulate a double tank system with a PID controller as our final project!

I somehow got here without having a clue what this about, and while the comments have only confused me more, I am thoroughly convinced by them that this must be a great video

Hi thanks a lot 👏 I‘m a remote pilot, I work with drones. Was having trouble understanding the PID tuning. Watching your example brought everything to light 💡 Take care 🍀

Am I the only one watching without even knowing what PID is? 😂

Very cool. Everyone in the Instrumentation world is smiling while watching this :)

The lack of sound or music made it even more educational. BRILLIANT!!!

That explanation in the description nailed it so well! Thanks a lot for the video and the explanation!

Having recently completed a Master course in robotics, I really wish I’d had one of these, or been assigned to build one. So clever and clear.

This explains why everyone attacks me first at the duel arena.

I was trying to find a demo like this after watching a couple videos talking about the principles. I could not find one then so I was planning to implement one by myself. Glad that UKposts recommends this video to me!

This is such a good demonstration on how the tunings effect reaching steady state. I’d be interested in making one!

Me: *aggressively searching for a map* This video: "Took a wrong turn in the algorithm didn't ya?"

OMG that is effing genius. I just wanted to see more...

This has been by far the best explanation of how to tune my 3d printer heater PID! Thank you!

Absolutely fantastic visual demonstration! You could make a fortune selling this device as a learning tool!

One of my hardest undergraduate classes.... Come back to haunt me. NO PROFESSOR, I REFUSE TO FIND THE ROOT LOCUS.

I started my controls class a couple of weeks ago and this is really cool.

This video is what finally made it click for me when I was taking my control systems class in college about 3 years ago. I ended up getting a C in that course, but now I work with hydraulic control systems every day and I love it!

I think I understand the concept behind this video and its really simple explanation of how pid works and the impact of low and high values. Great Video!

This is really clever, thanks. It would also be interesting if you showed controller responses to error causes by pushing the sensor with your finger. Maybe a part II?

When new engineers is about to tune their first control system, i always go through the ziegler-nichols method with them. It takes away 90% of the confusion. Also, remember, that many tasks can be solved with using only PI making the tuning more straight forward. The D part is incredible at counteracting load change, which fx is the key to success in almost all heating and cooling systems.

Thank you for this, your video, without a word, explained to me in a few seconds what I have been trying to understand for who knows how long! Watching this, everything I have learned, trying to figure it out, just fell into place. Thank you.

Simply beautiful, perfect PID, love it

simplest explaination. Thank you

just passed system control last semester. i like how youtube recommend this now :)

Thank you very much.1 minute 28 seconds has cleared my 9 months intense work of understanding PID in vain.

Very nice! Best (and most impressive) as well shortest and no word description of PID loop!!!

Believe it or not, this helped with tuning my quadcopter , cool

UKposts recomended this video to me. I didn't knew what it was untill I realised it's an electromechanical laugh machine!!! And it's adjustable!!! Wow,the things we can see today!

Mho. Hands down, BEST explanation (w/o words of course)! Thank you. I'm sharing with the world.

For cruise control on an ICE car, the parameters can be set different for when the pedal is depressed vs when released. Transmission gearing, RPM, and available torque are all relevant to the settings. Anticipating the road slope is hard. The engine may not provide any braking on down-slopes unless manually shifted into a lower gear. This makes optimizing cruise control rather difficult with an analog controller, and usually means that drivers will shut off cruise control on hilly terrain.

Fantastic!

here i am, trying to fix a broken lamp and i stumble upon this, i have no clue what this is about but i like it

I learned this when I was 10 years old. I was trying to make a group of robots that had several "leader" bots and a bunch of "follower" bots. The idea was to have an algorithm that would select the most advantageous leader and then have the followers follow it around like a train with no physical connection. I had to suss out the details on my own by trial and error. I finally realized that I needed three algorithms to insure that the "train" didn't decay into chaos. My instructor was amazed. He explained to me that I had implemented a control loop based on calculus. Thing is I had not taken calculus yet and had no knowledge of it whatsoever! A demo IS worth TEN THOUSAND words and diagrams!

if you can’t figure PID without this video you shouldn’t be anywhere around technology

Now I understand the principle of adjusting the regulator! Thank you.

I’ve learned _something_ , i just don’t know what.

I’ve watched countless PID tuning videos and this, without sound just explained it all to me! I can now make my car idle perfect thanks dude 😇😇

This helped me with pid tuning more than hours of tutorials.

It should have a weight on a spring at the end of the arm. Then I and D would really come in handy.

Great little expo...takes it out of the gui and into the real world in a very visual way, would be interesting to see the effect of foc along with encoders.

This is amazing. I broke my brain trying to understand PID. After watching this a couple of times I actually understand what's going on.

This isn't what PID stands for, but it helped me some: P-rimary speed to I-ncreasing speed to D-ecreasing speed

Это лучшая демонстрация, из тех что я видел.👍

I was waiting for it to become unstable. Great demonstration, nonetheless!

This looks like a great build project for learning about PID controllers

Have to agree with a lot of the other comments. This is an excellent representation of what PID tuning can achieve. Nice job.

Для чего такой пульт?

Увидимся в рекомендациях через 10 лет

Thanks this is a seriously excellent visualisation to explain PID controller for those that don't know what PID its what's used to stabilize the electronic control of things like drones and other control circuit loops.

The description was a life lesson in itself. Thanks I needed to read that.

gf: i am home alone me: turns D all the way up

это просто шедевр!

Probably the best demo of PID control on UKposts.

I wish I had this back when in college.

Add lcd for display value

Wow, this is the most clear and easy to understand video about PIDs I've seen so far.... and its from 2016... thank you !

This single video explained a thousand words theory and function

Всё понятно. Спасибо.

The easiest way to represent PID controller effects on a system.I have never seen before...

This is really good for understanding pid tuning. Thank you 🙌

This is better than any explanation I've heard so far. I'm glad you made that box and the video.

adding physical interface for P, I, and D on my control schemes changed my life forever. Joint operating weirdly today? Just retune on the fly! If you ever remake this video you should add a part showing unstable positive feedback!

I graduated with a degree in mechanical engineering and I still don't understand what a fucking PID controller is. But that's what electrical engineers are for lol

Beautiful visual demonstration!

That's the first time I've run into PID hardware. I could play with that for hours. Very useful for robotics I should imagine. Thanks m8. Keep well. :)

It's already 2019. Still have no idea what this is.
