God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

Did you try reading a couple of distance measurments and f.ex averaging the result? Might be able to smooth out the noise from the sensor

[@featherbrain7147]

I like the fact your code does not use a library, so the computation is easily visible.

[@uatiger1]

Very Thankful to you brother. I am an Electrical Engineering graduate and I have studied Control Systems extensively in my degree. I studied the mathematics of PID controllers in excruciating detail. And never fully understood it and could never apply it in practice until I watched this video of yours. Hats off man.

[@cuturbs]

I usually don't leave a comment on videos, but man, this one is gold. I'm an almost graduaded eletrical engineer and I took control classes. They were full of math and theory and lacked pratical exemples and your explanation is flawless. Just earned a new subscriber. Keep up this excelent work!

[@dave4882]

As a controls technician, this was explained in detail in my classes. The number of engineering students comenting on this says a lot to me. This is a pretty good explanation of pid control. 4 things id like to comment on. The seesaw set up is a bit flawed, in that a response of say 5% matters a lot more when the ball is at the end of the balance beam than when its at the center. So non linear control situation here. 2. The use of a rotating servo utilizing a crank(the disk, is set up as a crank) also creates a nonlinear situation. These 2 items are probably the cause of some of your oscillations. 3. You showed it, but didn't comment on it much, that there is a sweet spot in most control loops. Outside of that sweet spot, it can become unstable. When you stopped the ball in the center at 8:45, you placed the loop back into its sweet spot and let the look regain control. You can tune a loop to control over a wider area, but lose fine control at the set point. Some loops will actually have more thsn a single set of pid values so that once a process upset causes the controled variable to get out of that sweer spot, a better set of pid values is used to regain control, until the tighter control values can once again be utilized. 4. Utilizing a small fan to blow on the ball would have been a good demonstration as to what a loop will do under a process load situation. When using only 1 control type.

[@bogdanmarinescu78]

I've read quite a few PID tutorials in the past and they helped me understand how PID works, but this is still by far the best explanation of PID that I've ever seen, and now I understand PID even better. Thanks and keep up the good work!

[@johnschmidt874]

I think it's the best explanations of PID control concept i've ever had. It didn't dive into mathematical model, but it gave concept of how PID works. It's good if you make another video on how to apply filters on the system. Thanks for making this awesome video mate. Edit: you've got a new subscriber here.

[@Evgen-Evgen-Evgen]

Yeah

[@MrScorpnok]

This controller uses the ideal formula for D i think. If the setpoint is changed from a value to another (or the measured value...)in this case if the ball is moved from one point to another, the difference between measure and setpoint will instantly change and so the D will jump up to infinite for a moment (error-previousError/TIME)... In reality a filtration constant is needed. The shaking in this is probably is due to te inaccuracy of the measuring device (the measurement value jumps in steps instead of smooth rise/lowering) for that you'll need the filtration timeconstant, which will limit the jump of the D-control. Don't really know how to explain better without bringing laplace-functions to the table... Laplace functions are imo the easiest way to show the principle but i'd have to explain how they work...

[@MrScorpnok]

So, lets assume the system in this video checks the balls position every 1 ms and the accuracy of the measurement is 5mm. If the ball moves really slow, lets say it is 20mm away... it can move a few mm (to 22mm) before the measurement device reacts, and when it reacts (at 23mm), it'll think it has moved to 25mm. Now that the last measurement before the change was 1ms ago, the derivate part calculates 5mm/1ms, even tho the ball would be just barely rolling. The speed calculated with these values ends up being 5m/s. This makes the excessive back-n-forth movement. I think you might have already figured out why the filtration is needed but anyways... I was bored so I explained anyways :D also this didn't help at all with what you were asking which was HOW to make the filtration XD

[@MrScorpnok]

Elimination of derivative kick is a good term to google

[@akkudakkupl]

@@MrScorpnok You can also just get rid of the D term if you are okay with a bit of overshoot. Most real life process automation just ditches the D term because it has destabilizing properties :D

[@miiroderrick8821]

Was researching about PID temperature controller, I found my self on your video, then I wanted to get more explanation on PID control systems, KZbin brought me here surprised you're the same person to offer both my interests and I don't need any extra video. Honestly, you're the best I have ever seen in electronics. Thanks for the simple and creative illustrations.

it’s 2:39am in the UK and I need to get up at 6:30am. This has made my day already! thank you so much for putting this together.

[@WillHenson2009]

One of the best practical demonstrations of PID I've ever seen, fantastic!

[@clairecelestin8437]

Seeing the behavior of each component in a real system made it absolutely clear what each expression does, and how they work together to hold the system at a specific value. This was a really great demonstration.

[@PhilippeCarphin]

I spent at least an hour last week trying to find a video on PID control for my friend and none of them including the one I selected were as good as this so I'm gonna send him this one immediately.

[@mibrahim4245]

if you explain it simply, you understand it !! YOU'RE AWESOME explaining the PID parts .. - Mechatronics engineer

[@ranashreyas]

This was such an amazing explanation, mostly because you used a physical model and tested it; no other tutorial has actually implemented it. Thank you!

[@RiteshNEVERUNIFORM]

I really needed that

[@ramonmorales4937]

bruhhh my teacher doesn't want us to understand, he just want to cover the signature, even when he is a doctor in control systems. We know how to design a PID in math but not in real plants LOL

Apparemment je ne suis pas le seul français ici !

[@abhiramghanta9060]

this is one of the best examples that clicked for me

[@edgeeffect]

I've read about the theory several times without fully understanding but this simplified experiment makes it all very clear..... great stuff.

I know right! I totally agree.

[@GuyFromJupiter]

Higher gain values make for a faster reacting system, but they also tend to make the system very unstable if raised too high. This is especially true in systems with a considerable amount of dead time, which is the time from the PID changes its output to when there is a response from the system as measured by the sensor. This is why PID controls always have to be tuned for an optimal balance of performance and stability.

[@nieldewet5315]

What a brilliant and intuitive explanation. No lecturer of mine could ever explain it like this.

[@wikrap1]

You actually closed half year of lectures on my studies in 3 minutes... :D Very practical approach.

[@donstillwell9894]

Excellent demonstration of PID control. We are going to build your PID project to use in our maintenance training, where I work, to hopefully give our maintenance team members a better understanding of how a PID control work and how to tune a PID loop. Thank you very much for taking the time to make the video and sharing it with us!!

[@jiangxu3895]

Best PID explanations. I’ve gone through many tutorials, none of them explained well to show the importance of each parameter. It is especially difficult for me to understand the integrate of distance, when the differentiation of distance is equal to speed, which is much easier to understand. Anyway, great video. Keep up!

[@ShopperPlug]

This is really a cool PID example, like the fact it is using a LIDAR. This is the best explanation of PID and how it works.

[@RafaelKarosuo]

As many other have said, this 14 minutes helped understand the PID control implementation in code, way better than a semester of my automation and control introduction. Thanks

[@ravindrasarak2007]

PID was always a tough topic to visualise but your demonstration made it really easy. Thank you so much.

[@sumedhburbure4173]

This is the best video on youtube to explain PID controller concept visually!

[@mrtspirit]

I have watched many videos however non of them put those keywords together. " While the P value is small, hence no error to be sensored to create any movements ,as a result of no changes also No D action to take a place " loved it .

[@santopino2546]

Hi, I work with PID controllers in the process industry 32 years now, to help simplify things, from experience, in reality a PI works fine with most processes, The D component may give an extra help in some temperature controllers.

[@JonathanWaltersDrDub]

My understanding is that D will help protect from overshoot. This will help eliminate wasted energy. I see this could be useful in driving economy or other autonomous vehicle systems. What do you think?

[@PowerSports]

@@JonathanWaltersDrDub cruise control is a PID system in newer cars

[@JimmyVelghe]

Indeed PI is in general enough to get a system stable, I only use D with very agressively changing processes. That being sayd good base explanation of PID control.

[@DhruvJaiswal-q1b]

I have to say man, you just instilled some pretty decent curiosity for control systems in me through this video. It is a very big thing for me as being an Electrical Engineering Major I was always terrified of control systems and control theory. Great video Keep it up.

[@kun_fu_taco4775]

You are a life saver my friend! We have a system that control volumetric flow and we are trying to keep the flow rate steady at very low flows, this is all controlled by a PID system and I had a hard time understanding how to input the values. This really helps! "If the error is too small, the proportional won't affect" This seems true because we have a harder time controlling the lowest flows which is probably not being detected by the system.

[@Debraj-HTC]

This video clearly explains the PID, studying each of the P, I, and D separately made me get it finally.

[@mcdran4549]

[@hugbearsx4]

Great! So now it's time for a video on PID tuning, right? That is, finding the optimal values for p, i and d parameters.

[@MrJordot7]

I work with PID control quite often yet this is the best way I've heard it explained! Fancy doing a slight development of the same experiment, but put a fan at one end that you can direct towards/away from the ball to model an outside influence? When you use a PID for cooling, the temperature of the coolant can change, which means your actuator may need to start providing 'more' even though it was at equilibrium.

[@electronics.unmessed]
