Re: [Paparazzi-devel] AUTO2 Standby throttle management

[Reto Büttner]

Hi Joseph

 

That might be a problem in altitude control, probably just a tuning issue. Altitude is controlled both by pitch and throttle. In your case pitch control seems not be sensitive enough and throttle control too aggressive. Try enhancing the pitch gains and reducing the throttle gains. Maybe vertical control is generally to weak and you fly permanently in the aggressive flightmodes, try enhancing altitude_pgain. Additionally you might give more margin (blend_start and blend_end) in the aggressive section, especially until the vertical controller is well tuned. For more detailed analysis a log would be needed.

 

Regards and good luck

Hi all,

I did an AUTO2 Standby test yesterday and the plane accelerates to full throttle for half the circle and repeats the pattern indefinitly

here is the video https://www.dropbox.com/s/g3sl68myu15lh7g/VID_20130626_163444.mp4

I'm using 4.2 with the ctl_basic.xml control. I couldn't get a log of the flight as my ground wasn't properly connected to the antenna.

Any idea where that might come from? I'm not using an airspeed sensor but I have one at my disposal if needed, I just want to keep things simple.

Best,

Joseph
