THanks for your kind words, i would suggest you to refer my stable flight video, that has some improvements in flight by doing accelerometer calibration.

You're welcome!

Please try watch the stable flight video and try following the steps in that, I think it should help

Can you tell me which part?

Normal esp32 dev kit allows you to have only 80Mhz clock for some reason, I was not able to find option for 240Mhz

I just wanted to see if there was any improvement in trying a new uc , but it was more or less the same result.

I will later, thanks

It’s there in an excel file, you can find it there clearly with price

Yes it is, just need to worry about weight and think of a mechanism to run motors with mosfet

I am trying to, I have recently moved to a different country for studies, I’m getting quite busy so, but I’ll make soon!❤️

Approx 11k bro with flysky fsi6 transmitter receiver

There is an option to change the pid time in the wifi code, so I am changing it there it self, when I upload the code, default may be something but then I change it in the webserver ip address.

That’s terrific, You need to change the motor write protocol, maybe use analog write instead of servo write.

I hope the video helps you in some way 😅

Hello, great to know this, but I’m not quite sure how to help you as I don’t know about your system. Can you frame the question better with elaboration?

Problem is solved now, some pins of esp32 boards get logic high whenever we upload programs or pressing reset button, I go through every pin and found 4 pin which are logic low at these conditions and now working fine, I choose pin 2, 4, 12, 25

This drone usually drifts and hence we have to move the pitch and roll at times to fix it.

@@pratikphadte can i get your mail id? Even after calibration my roll and pitch angles are AccX:-0.05 AccY-0.04 AccZ1.00 AngleRoll:-2.02 AnglePitch:3.01 AccX:-0.05 AccY-0.04 AccZ1.00 AngleRoll:-1.98 AnglePitch:2.97 AccX:-0.05 AccY-0.03 AccZ1.00 AngleRoll:-2.02 AnglePitch:2.97 AccX:-0.05 AccY-0.04 AccZ1.00 AngleRoll:-1.95 AnglePitch:2.84

That’s so wonderful to know, thanks, I am planning on it.

Thank you for this comment, I appreciate your answer, I am keeping this in mind and I made a few changes, i am still facing some issue in stability, my motors were very badly damaged so I have got new better motors, I will test your recommendations and see the results.

Yes he is my inspiration for all this! I sort of missed out on acceleration calibration, post that results were much better.

Yes this line is important, I think the WiFi runs on a separate core, so try calling this line after your WiFi code, or try setting the values lower than 400khz and see what happens, there are certain standard values.

Make sure your I2C connections are intact, also try shifting the setClock() after begin(), In my case these things helped to solved the halting issue in code

Have u try this esp32 flight controller????

It’s my pleasure, thank you!

The flight controller itself should cost you around 800 rupees or less

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.

I think you could do that, you have to test its APIs. I tried with a web page joystick and it works alright. The libraries I used were Esp32Async server and esp32 webserver

@@pratikphadte okay. Thank you

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.

Sure! This week!

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.

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

You mean the transmitter?

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.

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

Yes, I’m available for personal guidance on drone related stuff on my Patreon!

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!

Hello Trung, thank you for your kind words. I am amazed to see that you all are working on it! And good luck to you!. I would suggest you to watch my videos and the resources in my videos carefully to solve your problems. I am available on Patreon, if you would like to get personal guidance, I am doing it only for my paid members on Patreon, due to lack of time I am unable to help everyone, please take this is a good way, thank you! And I again appreciate your comment and your words!

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.

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

Thank you 😂!

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

Thank you bro!

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!

@@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!
