hello guys,
I am working on one quadcopter drone. where my vibration and all other parameters are pretty good but drone is having oscillation in roll axis. i am attaching the log file can anyone help me to fix the problem i am attaching the log file and video of the drone flying drive link. can you guys assist me to solve the issues. i tried some level of manual PID tuning but as i am newbie to tuning couldn’t able to solve fully the issue
Looking forward to your support.
You have much bigger problem than Roll rate.
How about the massive outputs oscillation from default PID’s? Other than some fiddling with Roll D and misconfiguring the vertical acceleration controller gains.
And not that it matters much at this point but the Notch filter is misconfigured also.
Pick one of these paths forward:
Arducopter Tuning Guide
Methodic Configurator
Out of curiosity where does the Arducopter firmware target come from for this board? Because I would suggest using Bdshot but that’s not in this firmware and I see no firmware in the Ardupilot repositories.
hi @dkemxr thanks for the your response. i don’t know much about tuning. https://www.youtube.com/watch?v=4pkSnBqA_m4&list=PLFPBjpbd5xKSGFJfuQJBPWOm-sGv0VxD1I followed this person youtube video and done all the steps properly. can you guide me to solve the problems which exist in my drone. As per the question i have 55A 4 in 1 esc this esc has am32 firmware installed and i am using dshot protocol. i am using zerodrag strix H7 flight controller they have provided me custom ardupilot firmware to use. i also attached my param file in my drive link. in case of needed please check it. in case if needed the firmware file i will attach that too in the drive.
Looking forward your support.
You already followed a non official method of configuring that did not work.
How about following one of the official AMC YouTube videos that do work? It will save your time and everyone else 's
sure @amilcarlucas . i will give it a go one time the official method. if still persist i will come back to experts like you guys.
Thanks
Well, they should have provided Bdshot capable firmware.
Why isn’t there official Ardupilot firmware for this board?
No idea @dkemxr they are indian based company who involved in manufacturing Flight controller. as i am from india i would like to give it a shot with there flight controller instead of going to matek H743 slim V3. as most chinese flight controller started disappear from indian market. can you help me to fix this problem. and can you tell me you pointed out i misconfigured notch filter can you tell me more about it too. so i can check that.
thanks
I wonder how they are distributing this firmware. Because you will want the current Stable version with Bdshot.
The Methodic Configurator will reset all to default erasing the mistakes from those video series and starting you over.
And it will automatically create a backup before doing it. But like any other tool you need to learn a bit before using it. And there are AMC youtube videos and documentation. Do each step correctly and it will work
i introduced the second notch filter 27Hz in my drone, it made my drone fly smooth. so the problem is resolved thanks for your support.
Adding an extremely low frequency notch filter, and not tuning the PIDs can not be a solution.
But hey, if you can not follow advice… and are happy with the results, that’s fine as well.
Maybe. Let’s see the log.
https://drive.google.com/file/d/1tihrLiMJrJZ1VP1X1HhLZgtqOeA1bRVy/view?usp=sharing - here is the link for the log file @dkemxr . @amilcarlucas i am trying side by side using the official method. as i dont know much parameters its taking little bit time
It’s improved, the output oscillation is reduced. But not from Notch filtering which is still misconfigured. And you may wonder why this log file is 455Mb? Because batch logging is misconfigured also most likely due to that video you followed. Set INS_LOG_BAT_OPT,4 Not 5, 4.
And the vertical acceleration controller gains are still wrong.
Perhaps some people will see this before they watch the Rosser video series. Probably not as it’s spread all over the place in Web and AI searches like a virus.
@dkemxr thanks for the heads up. will change that. anything else is there let me know.
Yes there is something else:
All of the issues you are having are avoidable by using the AMC software.
Just to re-iterate that the Notch filters are doing nothing as they both lack a reference parameter.
