Dear all, We have a customed airframe, and we want to tune the PIDs. Currently, the frame is extremely twichy in both roll and pitch directions. As I recall, the old version of QGC has the autotune of PIDs, but for now I cannot find it. Could anyone advise me how to tune the PIDs? Thanks

Only APM has auto tune function.

Yes that’s correct, Adrucopter has it, thou really would like the feature but it creates a lot of crash drones from past experiences with big quad low KV, so maybe ask the if this would be an enhancement worthy?

I think that makes the pid coordination very difficult, specially for customed airframes. Are there any advises that tell how we can do this in an easy way?

It is possible to port the autotune function from ardupilot, since the code explains it in detail, but I think it would be very difficult to pass it from the integration tests without working with the PX4 team.

Yes you’re right, what I meant by porting is actually using a similar logic to this, the implemented algorithm doesn’t have to be exactly the same nor the method. * b) records maximum "forward" roll rate and bounce back rate * c) when copter reaches 20 degrees or 1 second has passed, it…

OK, yea in that case yes it would be great to have auto tune on PX4!

My frame is QAV130, very tiny. Is there any existing frames that can work fine without tediously coordinating PID params?

Hi, when I looked into the tuning guide for multirotors , in PX4, it also talked about tuning the attitude controller. And here, the code you shared and also auto-tune, they all are about attitude tuning. What if the attitude controller is working fine, how to proceed with , tuning of velocity cont…

Where do you see the tuning guide for multirotors in px4?

You can never port code from Ardupilot since the PX4 project has a different license.
