QUATOS log plots - YAW rebounds

Postby afernan » Tue Nov 08, 2016 8:34 pm

I´m plotting Attitude. Pitch and Roll looks right but Yaw is showing something extrange (see first image) that doesn´t correspond with reality (see second image)

I´m using following command:

Code: Select all
quatosLogDump.exe -p -m 1000 -M 50000 --att -vpg 2 004-QUAT.LOG


Any help is wellcome

Angel, try setting Yaw Rate filter TAU to 0.07 (default is 0.01). This should help smooth out the bounce-back and restore the previous behavior (pre acro-mode changes). As you mentioned separately, lowering PROP_K1 may also help a bit... or just smoother yaw stick movement when releasing back to center.

Max:
yes I´ve tried to move up/down the Yaw-rate smooth (from 0.01 to 0.2): yaw behaviour efectively smooths but rebound remains in all cases.
