What Is PID Control? | Understanding PID Control, Part 1

Chances are you’ve interacted with something that uses a form of this control law, even if you weren’t aware of it. That’s why it is worth learning a bit more about what this control law is, and how it helps.

PID is just one form of feedback controller. It is the simplest type of controller that still uses the past, present, and future error, and it’s these primary features that you need to satisfy most control problems. That is why PID is the most prevalent form of feedback control across a wide range of physical applications.

However, often when learning something new in control theory, it’s easy to get bogged down in the detailed mathematics of the problem. So, this video skips most of the math and instead focuses on building a solid foundation.

Explore the fundamentals behind PID control.

Holy shit, This 12minutes was much more useful than my 2 semester of Control systems.

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 .

[ThomasFerguson]

Learned more in these 11 minutes and 41 seconds than I did all semester in my Feedback Control Systems and Instrumentation classes

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.

[joebloggs]

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.

[YMARihab]

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.

[drumrocket]

I am studying Electrical Engineering and after already passing Control Theory this is by far the best explanation to introduce this subject! Great Job!

[yosefstanton]

You're the only person in everything I've found who explains it! Saved my life!

[kerimmoral]

Well that voice and black screen teaching couldn't be someone else! Thank you again Brian!

[jacco]

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 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

[glasswhite]

Incredible. It only took 11minutes and 30 seconds to fully understand why P, I, D each stands for present, past, future errors. Thank you!

"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 YouTube until I stumbled upon this gem. The explanations were crystal clear, and I now feel much more confident in tweaking the PID settings to achieve precise altitude control. Thanks a ton for making such an informative and easy-to-understand video! 🚁👏"

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.

The knowledge you have gained lets you explain this concept so easily rather than half minded YouTubers how can't explain why PID is really used. This video is a great example of Feynman's technique.

[mustafapicak]

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.

[aaron]

I wish I watched this video before my first control class. I struggled a lot figuring this out

[caducoelho]

THIS IS SIMPLY BEAUTIFUL, MADE ME SMILE OUT OF SATISFACTION OF GETTING IT!

[vikasbansal]

Explaination is beyond excellent. I wrote it down all every word u say and all that. It take 14 pages and 2&half hour. 👏👏👏🙌🔥🔥

[nathanmurfey]

Brian you are literally my hero. You're videos have been helping me for like 5 years now.
