Switching between hall and observer

Hello Benjamin,

 

My use case is paragliding towing using current mode to get constant force on the rope. The speed of the motor slowly decreasing when angle of aircraft increases. I noticed some glitches on the ERPM close to switch between observer and hall sensors.

I added 'acceleration' to vesc rpm graph and really see some glitches: https://drive.google.com/file/d/1Zjigupop-Tyj5qj0amLei8AbIaCJNjYn/view?u... near 4000 ERPM. This is my 'Sensorles ERPM' settings in the FOC -> Hall sensors section.

Is it possible to reduce glitching on observer swiching?

You can play with different ERPM settings for Switching from HALL to BMF. As far as I know Benjamin tried his best to have a smooth transition. It depends on the motor and sensors though.
