New Filter Settings for vibrations Firmware 1.9.0

#1

‘Forgiving default filter settings for larger multicopters with high vibration levels.’
What are the new settings and where can I find them.

Thank you in advance.

Hi @Kennedys ,

The parameters are IMU_GYRO_CUTOFF and MC_DTERM_CUTOFF.
We changed the default of the gyro cutoff from 80Hz to 30Hz to increase resilience against vibrations (the dterm filter is disabled as the gyro cutoff is low enough). If you have low vibrations above 30Hz, feel free to increase the cutoff frequency in order to increase tracking performance.

Check out that link for more details on filter tuning: https://docs.px4.io/en/config_mc/racer_setup.html#filter-tuning
and about vibration: https://docs.px4.io/en/log/flight_review.html#vibration

Good luck!
