Autopilot setting absolute - Andreas29 - 2021-04-18

Hi,

should the autopilot setting asolute should work?
I tried this here at home. When setting the pilot to absolute (and set the gains) I got no reaction of the actuator when moving the IMU.
Before I investigate this deeper I want to know if this function is implemented yet.

I use the latest tinypilotimage.

Best regards

Andreas

I tested it last Sunday briefly and it did not work...

unfortunately this pilot has not seen much testing so I don't expect it to work yet... This pilot requires rudder feedback as well

Hi,

@Onno: @Sean: thanks for your replies.
Rudderfeedback was connected (and calibrated).
So I think it´s not a special problem of my setup.

Best regards

Andreas

Ok that is actually good news  Big Grin then we have possible use for our rudderfeedback!
Yes I also had rudderfeedback connected and calibrated, we will ad this to our issue list!


RE: Autopilot setting absolute - seandepagnier - 2021-04-20

so far rudder feedback is always used for end limits to avoid stress on the system, and also to output the rudder angle to nmea and signalk.

the absolute pilot is a basic attempt at a PID filter which incorporates the rudder feedback. I suspect up to 10-15% improvement over the basic pilot so in many cases it may not be possible to notice the difference, but as you can see I implemented this some time ago and never managed to test it (too many other things to test) It could be especially useful if there is a lot of weather helm.. will be interesting to see.
