Alexmos brushless gimbal PID settings : share them with the community

Hi,

It is very hard to tune a brushless gimbal. Even the best tutorial found on the internet are hard to replicate because we all have different setups : cameras are different, hardware is different, Voltage input to the alexmos board is different, etc.

Let's share our PID settings to constitute an as big library of settings that works as we can. Either you will have the same configuration as someone and you can just copy the settings, either you are close to a published setup and then you can start from there to tune your particular gimbal.

Please post:

-Gimbal hardware : make or model

-Camera : make and model (specify also if you have particular lenses as the weight changes with differetn lenses)

-Brushless motors : make and model, number of turns

-Power , P, I, D for pitch and roll axis

-an eventual youtube video to show your best results with these settings

 

My turn:

-Gimbal from kamkop.de

-Camera : NEX5R with 16-50 lens

-Brushless motors : GMB 5010 - 150 turns (copies of RCtimers I think)

-Battery to alexmos board : 4S

-ROLL : Power : 120, P : 20, I : 0.17, D : 18

-PITCH : Power 50, P : 17, I : 0.15, D : 15

Your turn now !

Hi Everyone, 

I have some troubles to tune my brushless gimbal. Here’s my hardware : 
Gimbal : Beholder MS1
Camera : Blackmagic pocket cinema
My PID settings :
I actually don’t really know if it’s a tuning problem. When my Beholder MS1 is connected to my computer, it working properly if i turn it on (i just need to calibrate it). But as i deconnect it from my laptop, the Beholder is going crazy, shaking in every direction. Even if i don’t launch simplebgc : i connect the usb cable, the beholder is okay, i disconnect the cable it’s being crazy. I tried with two differents usb cable and the result is the same. Anyone could help ? I’m kind of disappointed right now.
Thanks all,
Oliver.

Here is the settings I use with a Gyrox 3 and Hero 3 + black.

Hey guys, I need to know if my gimbal config were good.

I use 2 axis alexmos with 2204 260kv motor on roll and pitch.

The camera was Xiaomi Yi that weigh around 70 gr.

The setup I've been use was GoPro setup with these value:

PIDs:

Roll: P = 15; I = 0.4; D = 25

Pitch: P = 5; I = 0.2; D = 11

Powers:

Roll = 80

Pitch = 55.

I put these on my custom F450.

When not flying, the gimbal worked good. But when I flew these with my quad, the gimbal became unstable, moved like crazy. I try to give more power on setting (180/150), the condition became worse when flying. Otherwise, normal when not flying.

I saw another gimbal using 2208 70kv/80kv/90kv. I used to use that gimbal too with same camera but there was no need extra effort in PID and power setup. Curious.

What is the root of my problem? Is it PID setup or my gimbal's motor kv?

Guys, are you sure this is the best approach to set your gimbals' PIDs? I'm just thinking out loud, but there's WAY TOO much variables constituting to your gimbal's performance, never mind a person's personal preference to set a gimbal less / more aggressive. 

I watched this half hour video discussing the PID setups of different PID parameters and respective effects (from first principle basically), and must say.... this guy knows his stuff. It helped me to figure out my gimbal

Auto tuning works pretty well with newest SW for most of the setups. Filtering has big influence on many setups, and on Advanced tab is plenty of useful stuff.

If you are tuning aerial gimbal, do not forgot to tune your FC also and RC control setup affects a lot the end result.
