Re: [Paparazzi-devel] First Flight lisa/m fixedwing...throttle auto 2 problem...

[Jorn Anke]

Hi,

Last time I was flying with the Lisa/M (maybe 10 months ago) there was, as I understood it, no use of the onboard aspirin barometre. So altitude must have been taken from the gps, which in turn must have ment the altitude was estimated pretty roughly. At the time, also I observed throttle was used extensively - which I believed was because the ap was trying to correct for perceived altitude deviations.

Out of curiousity; could the throttle behaviour Luis has observed have anything to do with handling of perceived altitude/ lack of correct barometre settings?

Cheers,

J

I think you auto throttle P_GAIN  is too high.
For the first flights use throttle I_GAIN as 0 (zero)

BTW, i think roll setpoint as 35deg is too low.

Voce ainda nao disse qual seu uso para o paparazzi.

Hello Luis

I think you must to change nominal cruise throttle , you can fly in manual
and find exact value of throttle in GCS.

Also, it's better to change Auto throttle PID gains.
