Tuning PID from Log Files?

Postby wangyeee » Thu Apr 02, 2015 11:03 am

Is it possible to calculate proper PID values from AQ log files other than the methods described on the wiki? If it's not feasible, can I tell from the log how to change the current value, e.g. a too large tilt angle P needs to be reduced?

Read the info in the wiki.

http://autoquad.org/wiki/wiki/configuri ... de-tuning/

You can increase and decrease the Max Tilt angle many ways but changing just Tilt angle P does not change the Max angle. If you increase the Tilt P and Increase the out Max you can get a larger Tilt angle.

You can increase of decrease your Tilt angle by increasing or decreasing the Pitch and Roll scale factor on the config page in the QGC.

Thx Larry.
But I think I haven't make myself clear. During my tuning process, I found it was difficult to distinguish high/low frequency oscillation. The quad seems to be always oscillating at some frequency. So I want to find some clue from the log file.
