Lat_contrl_period & damping not available

Hi, I am trying to PID tune my USV using ardurover 4.7.0. Frame class boat. I am very close but have a touch too much overshoot.

I cannot get my options for LAT_CONTRL_PERIOD and LAT_CONTRL_DAMPING in basic tuning page, they are there but unable to be selected.

I also cannot find any NAVL parameters in my parameter list.

Is this because i am using a boat frame class is removes these parameters. I am using a kayak as a boat hull and it is heavy with quite a bit of momentum. I have my PID tune very close.

Thanks

Hi @sebbirkner,

Thanks for the report. So to be clear it’s these Mission Planner fields that are blank that is the issue. This has happened because Mission Planner hasn’t kept up with changes to the main flight code. I’ve raised an issue to have those fields removed.

Our tuning pages are here on the wiki and remember to do the speed tuning and turn rate tuning first before moving onto navigation tuning. Often no navigation tuning is required actually.

I wonder where you read about the NAVL parameters? They’ve been gone a long time and shouldn’t be on the wiki any more.

Txs again.

Oh ok great now I know thanks for the info. Not sure where I got it from but will maybe check to make sure they know it no longer exists.

Yes I have done steering and speed tuning first.

Thanks again!
