In the config page for Arducopter of this MP's new version what is the additional "I" parameter in Loiter - Nav WP - Throttle Rate.
It looks like writing a parameters file with this new version and previously saved with a older version of MP gives unstable flight in stab. mode and do not work in alt_hold and loiter.
Hi Jean Louis, please upload here your old configuration file and the "new" saved with the latest planner after the import.
Please write a note of the ArduCopter code for both file, like "2.5.0" (old) and "2.5.4" (new), thanks.
Here are the files. I have noticed that in the new mission planer there are at several places with two "I" parameters
Loiter-Nav WP and Trottle-rate I could not find any explanation on those new parameters may be this is the cause of my problem,the old file "Last1-2.4" works pretty well with previous MP this same file loaded and written to APM2 "Last1-2.5 with the new MP is a nightmare to fly my copter !
I compared the files, I see no vital signs unchanged for what concerns the stability and rate, so your quad has to fly with them.
Concerning the 'I Term " I suggest you to read the wiki on the general functioning of the PID, because of this we are talking about.
We are arranging the automatic functions, once we are sure of being on track to update the wiki section about "Loiter" PIDs.
I recommend a "full reset" of your APM2 from the "Terminal" section inside the planner, then reload your old parameters and leave me a message if you still have problems.
Always remember to keep the planner updated to the latest version.
Thanks Marco for this super fast response.
I will certainly clean (Reset-erease) and restart on good basis with new MP version.
Concerning the PID my real question is why for : loiter - NavWP -and throttle-Rate there is now two "I'''s
In any case I will keep you posted on result after following your suggestion.
I don't know if this helps. But when I got the MP 1.1.74 They didn't have the two I's. Is it possible that in 1.1.73 that the extra I was actually supposed to be the D
Yes, Jl there's something wrong in your planner, dunno why.
You read this two extra i-term only when you try to load an old configuration file? :-)
In my planner the "second one" is no"I" but "D".
looks like the problem comes back to a language translation issue. the order is P I D, the field is just mislabeled
You are probably right concerning the mislabeling for the french translation but there is something wrong at least in the loiter box when I load the same file the "I" term that I have adjusted to 0,001 in the old mp version 1,1,60 is becoming 0,200 in the version 1,1,73
Since I follow closely everything going on with this beautiful project I would prefer to get my Mission Planner updates in English.
Is it a simple way to get all the update in english or how easy is it to download the English version.
jsut goto config > planner > language
I switch to the English Mission planner 1,1,73 !!! no more confusion.
I loaded the vers.2,5,4 and made few changes ,it looks much better and my quadri is flyable now.I still have to do some tuning for Alt_Hold (the quad is climbing slowly but surely) and for the loiter for more accuracy on the target.Today it's very windy here so will see tomorow for some additionnal tuning
Thanks to both Marco and Michael for your support very appreciated.
Here is the file I am using
