Hi all,
In search of the holy grail of altitude hold I was studying a couple of my logfiles.
Plotting [log_radio_channel5] against [log_gps_height] and [log_ukf_pres_alt].
During altitude hold the graph shows [log_ukf_pres_alt] a relatively level line and [log_gps_height] a slowly descending line.
Physically my quadcopter descends slowly.
If the controller uses [log_ukf_pres_alt] to determine height it doesn't do much, because it's level.
Now I'm wondering, how do I determine good altitude hold from logfile data?
And how does the AQ controller do that?
Best regards,
Jan Willem
