Yup. This is the best example

Bravo!

If I wanted a motor to turn a shower knob for SS temp control (due to dishwasher, toilet, etc using cold water heating up the shower water), how would I program the TC and motor to adjust valve position? I don’t know if a single shower knob is linear or equal percentage.

Is my understanding correct? The PID output is the voltage of the DC motor. This is proportional to the 2nd derivative of the position for which you give setpoints. Is this normal for PID controllers that the output is the 2nd derivative of the input?

Damn this is the best explanation of PID I've ever seen and it's in under 3 minutes

I don't do control systems but I did IT work in refineries. Why control systems engineers needed advanced degrees makes a lot more sense now.

engineering beuty

Creative video, thank you:)

Do you know the LM 628/629? Great job

Hi, I'm a student from Poland and I'm currently writing an engineering thesis. I am building a servo drive station with an electric motor, I have a problem with building a regulator in simulink. Are you able to help?

An absolutely amazing demonstration and final result!!!

If the impulse response is tested and formulated, can the PID values be calculated for the desired response? (Instead of manually tuning them. )

I never quit knew how to prevent windup properly, i used to just reset the error when target was reached and it "worked" but was not how it should be done. Had a look at your code and now have a better understanding of how to do it

Video so good you did all the teaching my proof needed when showing this to our entire lecuture lol

You actually deserve more than a million views until now :)

Hi Gregory, nice content! Do you authorize its download and use as support content in a educational simulator? Thanks

do you have the other example real system controller like LQR, fuzzy logic etc

The system looks so stable that you can get away with ditching the integrating part and just use a PD controller.

Plz, i need some one to help me to make this project.

This looks like a space state model Is torque the input just as the math model?

Thats a fantastic job!

Great video, clear shows the function of PID. It is much better than many explanation videos with too many words and formulas.

Can you make a tutorial for this? I want to try it

awesome

How do you know what numbers in Kd, Ki, Kp use in this PID? Can you model that system?

i couldnt more understand of what this system is really is.

super helpful! though god pids are such hell to make and account for the numerous errors and stuff!

Currently working on a DIY PID controller for homebrewing, I have just finished some tests and also ran some auto-tuning methods (Ziegler-Nichols), now I have the maximum overshoot down to 0,1K, which is really nice. But boy, it takes time! The output is used as PWM control for an SSR with a cycle time of 5 seconds. It must be fun to work with a system that reacts so fast like yours, you get instant feedback and can tweak more or less in realtime. I think, I'll build something similar, just for fun!

You are amazing , thanks a lot.

Finally a great demonstration to help us visualize these ideas!

Best explanation of PID I've ever seen.

I heard about PID control from people in the BBQ world, but had no idea what it actually meant. Now, I am weeks away from getting a degree in Mechanical Engineering and I have a much better understanding. Your video really solidified everything and provides an excellent explanation of PID control. As a side project, I am going to build a PID controller to regulate temperatures of a smoker with the use of a fan.

At GeorgiaTech, Atlanta, I've had the change to physical watch this demo in ME6405 course with J. Rogers. Great job Gregory ! 👍

Thank you so much for this video!

Everything comes with price - LOL - in this World we can not get the PID adjust instantly and acuratly. However it did great job.

Bro can you help me build a maze solver robot??

Awesome video! Thank you!

Great demonstration. Could you let me know what motor you used as the one that is listed on the Ebay link is no longer available, Thanks.

this is awesome, thank you for this!

best PID illustration video I have ever seen.

Jesus Christ this is going to help me so much 😅

Why do i found this video in my final semester???!!! 😭😭

spanish?

Now that is an awesome video. Thank you for doing this.

that's beautiful

Great Demo!!! I am trying to build a demo exactly like this using a Arduino microcontroller and I am wondering if it is actually possible and if your code can be converted to work with an Arduino instead of the Texas Instruments controller? I also have a question regarding the type and model of H-Bridge your using in this example as well as what the resolution (pulses per revolution) your using in this example. Any help you could give me would be immensely appreciated. Thank you!!

Where is cod?

Great video!! thank you!!

Very nice 👍

I was a Motion Control Engineer in my very first job 25 years ago, long before robots were cool like they are today. I worked on streamlined robotic arms inside wind tunnels, satellite tracking TV transmission vans, formula 1 racing car "4 poster" testing rigs, air-to-air missile testing systems, and tank tracked robots that would crawl inside nuclear reactors using neodymium magnets that hugged the surface so they could drive upside down held up by magnetism! At their core, all those projects worked because of PID control of DC motors. Some days I wish I'd staying in that industry... :-/
