Betaflight 4.2 filter tuning. The easy way to get a perfect filter tune!

Рет қаралды 113,454

Hi Everyone,
In this video I go through:
1. The theory of Betaflight filter tuning
2. How to set up gyro-scaled logging so you can look at your gyro noise
3. How to view those logs in Blackbox explorer to see your gyro noise
4. How to use the information to get your perfect filter tune first time every time!
This filter tuning approach is pretty much the same as that used by ‪@uavtech‬. I didn't invent this but I hope that this explanation is helpful nonetheless.

Sweet video Chris!! 9:40 - one minor thing: -3db is 71% of the signal amplitude gets through. It is 50% of the signal power, but we are not interested in power. Power doesn't mean anything in this application. That was a common confusion even with some lead devs till about 3-yrs ago.

@@PIDtoolbox Should be fine because you are looking at the power spectrum, not amplitude spectrum. Problems only arise when comparing power to amplitude. You'd need to compensate for the square root (or the squaring, looking from the other way), so you'd need to multiply by 2, like UAV Tech pointed out. Power ~ Intensity^2

@PIDtoolbox 3 жыл бұрын

Gotcha, thx guys. Yes, there’s a amp^2 and multiply by 2 in there in a previous step so that’s good. I’ve compared it directly to various other Matlab build in functions and it gives the same result. I just like to compute it myself so I don’t need as many Matlab toolboxes to make it work. Nice to have confirmation.

Hi Chris, I did this with my catalyst machineworks shocker tank, I did to mine, that which I asked about yours below, ie tightening up the min and max for dynamic notch and D-term, leaving a 25hz margin either side. I also noticed that my motor noise only showed 2 harmonics within the band range on explorer so dropped to 2 accordingly. Also no gyro filters as gyro debugging showed nothing. I have to say, even with deliberately abused props with extra notches (small) & some tips cut off, it still flew fine, not even warm motors and totally clean charts for gyros. FANTASTIC m8, thank you so much. Cant wait for pid tuning, coming soon. Best wishes to you

Using the waterfall prooved super essential to find my right filters. Thanks for explaining even a bit more on how these betaflight filters actually work. What I would find good: Could you show how it looks when your filters work properly? Like showing before-after waterfall graphs and also some gyro+pid graphs? I got the noise of my quad down significantly, but still have the feeling that the signal to the motors is kinda noisy and thus wasting a ton of energy. But a bit of noise in that motor-signal seems ok if I look at UAV tech logs? Hard to judge!

Fantastic work. I 100% agree with this logical approach and strategy. D term is the limiting factor and just randomly cranking it up to cope with frame resonances and motor noise just leads too disaster. Only really experienced pilots can get anywhere near a great tune by feel - I'm not one of them. A quantitative approach is the best way. Watching you and UAV Tech over the past few months has totally consolidated my existing knowledge and I can now fine tune with 100% success. One thing I'd add, just flying on default BF filter and pid settings and then analysing the data is perfect for 5 inch. But something , say with ducts and a poor frame build can fry motors extremely quickly. I always do a quick LOS shakedown flight in the garden for a minute and check temps for before heading out for the first proper tuning flight. If they're not stone cold something needs looking at.

All great tips.. thank you.. i think one quad issue was battery strap pushing wires so they'd touch gyro. Since then and working on gyro filters in inav I've got it flying better

This is amazing! Best structured filter tune guide out there! Great job 👏. Any chance you can make a video tuning filters on Emuflight with no rpm filtering?

I have to be completely honest, I wouldn't recommend anyone fly a quad without RPM filtering its such a keystone feature. I will cover Emuflight when they implement the feature (I think it's coming in 1.0)
