The UAV experiences high-frequency vibration during hovering and trembles when descending.
Post a .bin file. But that is a very commonly posted issue in this forum.
you can use the many existing answers to fix it.

The outputs are oscillating badly from default PID’s, default motor ranges and incorrect vertical acceleration controller gains. Looks like this:
Do you have foam covering the barometer?
Take one of these 2 paths forward:
Tuning Process Instructions
Methodic Configurator
First of all, thank you for your solution. Below are the unsuccessful attempts I have made:
-
No sponge covering was used. (The temperature was around minus 7°C during the test; I have added the sponge today and will conduct another test shortly.)
-
The notch filter/throttle filter was enabled, but it did not improve the situation.
-
Reducing Roll.D from 0.0036 to 0.0025 also failed to work. (AI analysis indicated an abnormal Rate.R.)
You need to cover the baro.
Forget about AI it will lead you astray.
You cannot configure the notch filter with oscillating outputs.
Either follow the Arducopter tuning guide thru completion or use the Configurator.

After reducing the P and I values of the throttle acceleration, the descending vibration disappeared. The high-frequency jitter during hovering still persists, and it is now suspected that the battery strap is interfering with the IMU.
Changing the position of the straps did not work.
Post a link to the flight log. And viewing IMU Gyro output is not useful.
