Beta release 5.0

Postby lukasz » Thu Oct 14, 2010 1:38 pm

Hi Tom,

I have couple general questions regarding latest Beta release:

* Height to pitch PID can be tuned

Can you let me know how this should be properly configured?
On wiki page we only have information how to configure "P" roll and pitch.

* Aileron differential added

Can you share some more light on this?

* Automatically go to navigation mode when no valid RC-signals are detected

Is this valid for both PPM and PWM signals from the receiver?
How does the gluonpilot identify the lost of RC-signals?
What happens to throttle when we have RC-signal lost?

Hi Lukasz,

Thanks for your questions, you're right, maybe I should be more elaborate!

* Height to pitch PID can be tuned. There is a feedback loop "altitude error" -> preferred pitch angle. This is configured in the lower right on the PID tab-page. A P-value such as 0.03 should be fine. In the previous version this was hard-coded. Now you have more flexibility!
* Aileron differential: In the control tab page. If you want to turn left, the left aileron should more (creating more drag) than the right one. This will improve the yaw movement. On flying wings, this has some kind of "upward pitch" effect on coordinated turns. In the future I might add (or change this into) a "roll angle to extra pitch increment" variable.
* Automatically go to navigation mode when no valid RC-signals are detected: This only works for PPM signals. Throttle will stay at the last correct received value. If you use PWM-signals, you'll need a receiver with failsafe mode (and you'll need to read your manual :-))
