PID controller Simple explanation with a Quadcopter as example. 

Thank you for your kind words, I appreciate it!

Thank you so much!

Thank you brother!!

Thank you so much!

Thank you so much!!!

Sure! This week!

Yes sir I agree, I wanted to mention this method. It is being used in the pixhawk flight controllers. Thank you for sharing your input, glad!

Yes they are! You are right safety is top priority!

Thanks

Yes you’re correct, I noticed it. I’ll keep this in mind for the next videos. Thank you for pointing it out.

@@pratikphadte it's ok bro all the best

Thank you bro ♥️

Thank you brother!

Thank you for your comment, made my day! 💪

Thank you, nice to meet you!

Thank you so much!

@@nightshowdown4178 thank you for subscribing and supporting! Thank you so much!!

@@pratikphadte hey just wanted to give you suggestion would it be better if you upload code explanation series like carbon aeronautics or joop brokking that what you entire code is doing and how an individual can make it ? just a suggestion hehe🙂

@@nightshowdown4178 ill take up on it, but the thing is Carbon Aeronatics and joop have already done a god jobs, to recreate it, it seems like a re work. But never the less, ill try making. I have some more good stuff coming UP. I really appreciate your suggestion and advice, thank you so much for supporting!

Thank you bro!♥️

Thank you Manoj for the idea on the stand! Glad to have connected with you! The stm32 quadcopter is crazily stable!

Little bit of both i would say, Thank you so much, made my day! 😊

Yes you are correct, I made this video for people to understand learn about a pid controller and not specifically about the drone. You are right the values will change when I fly the quadcopter independently. I hope my answer makes sense.

My man Sasmeet! Thank you!

Thank you!

Way to go man! Excited to hear your ideas, would love to see your progress, subscribing to you right away!

@@pratikphadte dude. Is that a linux computer

Yes! It is, helps with ros2

Thank you for your reply, however I could grasp it not so well, if possible can you share me some resources I can follow, especially the dual loop part. And yes you are right about the rod, i made this video for people to understand and learn about a pid controller and not specifically about the drone. You are right the values will change when I fly the quadcopter independently. I hope my answer makes sense.

@@pratikphadte I'm not sure if I can post a link as yt sometimes blocks the comment, but the term to search is mathworks cascade control loop for example.

Removing the integral gain for this specific constrained system may work due to a lack of external perturbations, but will not work in-flight. The "I" gain helps mitigate lots of external factors such as mass imbalance, wind gusts etc. A quick check is to see what happens if you put the battery to one side of the frame instead of the center with no integral gain. From experience I can tell you that your vehicle will (in this constrained setup) stabilize at a non-zero roll angle. In-flight this would mean your vehicle will stabilize with a coupled roll-pitch tilt and fly off into the sunset. ;)) Furthermore, two control loops generally make sense when you have time-scale separation, e.g rotational and translational dynamics where rotational dynamics are much quicker than translational. Then you could have one loop for stabilization (rotational dynamics) as you have now which operates at relatively higher sampling rates, and another one for navigation/guidance/waypoints (translational kinematics/dynamics) which operates at lower sampling rates, typically a difference of 10x. Then you could have the outer loop (slower) command attitudes from the inner loop (faster) for translational motion. @pratikphadte, loved the work. I did something similar on an Arduino Mega last summer. Worked out for a bit, but as you may have figured out from your own experience, quick and responsive PID control and stabilization across the normal flight envelope is not something that boards like an Arduino or an ESP32 handle well with their relatively massive overhead. Switched to an APM 2.8 and later to a Pixhawk 2.4.8, couldn't be happier today with all the flying that I do and the additional functionalities they offer. Good luck and happy flying!

Thank you bro!

Yes you are correct, I made this video for people to understand learn about a pid controller and not specifically about the drone. You are right the values will change when I fly the quadcopter independently. I hope my answer makes sense.

Yes I agree, again this video is to demonstrate the PID controller and not to be referred completely as a guide to tune your quadcopter.

Thank you for your kinds words, can you please mention the timestamp? If you are talking about the very high oscillations, it’s because of the overshoot in the p controller.

Hello bro, I’m excited to hear about your ideas, you should just dive in them. I appreciate you asking me for advice, I want to help you and I get many messages asking me for help! But I’m occupied by my work and as a creator time is super valuable, I would be able to help you better if you take up my Patreon as that supports me. Thank you for understanding, no hard feelings.

😂😂😂 right on

Thank you, yes I’ll approach if required!

@@pratikphadte NO problem, you are welcomed. And you can find my contact in channel info.

I did, super thanks!

Thanks, you can check at robu.in

Hello, the results will vary as this is done on a stand, and the system is different from an independent quadcopter , I suggest you to follow a p value of 0.7 and d value of 0.008, I you can keep 0

@@pratikphadte see in my drone correction are happening but in your case the drone is in center stable that is not happening

CS is the language, math is the song 😅

@@pratikphadte Were you trying to say the other way around.

@@ckush928 nope 😊

The pid values are kind of related to the drone system so ideally it’s never the case but fast fc like thee speedybee have a good processing speed and that makes their pid values workable for a broader bandwidth of Systems, they may give the most perfect result but it’s almost satisfactory.

I have showed one in my pid WiFi tuning video, check that one, also there is a small 2 min video showing the flight, you may check that as well.

My audience is very niche I feel that’s why I make videos in English, but yes I can work on that idea. Thanks

Yes!

@@pratikphadte Thank you for good video. Can you give some guides or resources which we can use to make ESP32 drones?

@@nikitam4677 thank you so much!, please check my diy esp32 playlist for esp32 drone.

Hello, please follow the WiFi tuning video, in that I have mentioned how to get the ip address of the esp32.

@@pratikphadte I figured it out! Thank you so much, and I hope to see more videos about quadcopters from your channel in the future.

is the code working properly and making the drone stable

The purpose was to explain pid and I didn’t have an apm 😅

Follow the resources in my other videos. Joop Brokking and carbon aeronautics are the best out there.

No it depends, if the fc has good clock freq then for better working I can select a lower time cycle which can sort of give me pid values which will be different Than the esp32 pid values

@@pratikphadtewould it be same for arduino uno and amp2.8 as they both have 16M hz , will it be same?? . Because i am trying pid tuning but facing problems using the arduino .

Can’t say for sure but yes

@@pratikphadte bro have you done this thing on arduino

No I haven’t, you can check joop brokking for Arduino fc

Hoi bro, Kide mhanta? Ghat?

Ghat! Just discovered pid controllers and found u, vids powerful asa, really helpful. Good to see u use linux. Is it always the case ?

@@TanmayGaude23e4 thanks bhava, no Linux is not necessary, just better for Ros

I from mechanical engineering,I want to learn more about Robotics,can you suggest me how to go about it,I am from Goa

@@beastlyy858 yeah please refer articulated robotics for mainstream robotics.

You’ll get it working! Keep up the work!
