I just talked to my father, A/C maintainance instructor for Airbus Fltight Controls and Engine, so I think he should know about it. (hopefully ;-)) ) To bring some light onto things, how it is done on real A/C. Yaw damper untit: prevents only a dutch roll (caused by yaw movement) by acting ONLY on rudder not on ailerons. FCPC (flight computer) does this, if offline, a backup yaw damper unit is there. It depends on A/C aerodynamics wheter the plane starts to turn w/ bank angle != 0 or not. Usually the plane does not, so FCPC is mixing some rudder to make the plane turn. Which force would else make the plane turn? And I'm sure Bank Angle does not, may help a little bit. Anyway, first results based on error on y-axis accel gave good result.
