PID tuning

[Shumatic]

Thanks for giving us this enhanced SW

I installed it on a LGT8, with Arduino, and it works fine

But i have some quistions about PID tuning.
I have run PID tuning, and uploaded the values on https://pidtuner.com/

But theres a lot of quistions, firstly on
Selected Time Range i get 14.03 to 125.86
on Pre-computed Time Ranges, theres an option xto choose

• 14.03 to 24.45
• 14.03.to 98.81
• 14.03 to 125.86 - i selected this

Next i get to choose Model

• 2nd order
• Integrator with lag
• Integrator
• 1st ordre
• Double Integrator

And i have no clut what to choose, and it dosnt match with the option to set 10 pid constants in the sw

Could you plase give me a hint?

Hi Schumatic!

Well, PID Tuning might be really complicated, in special for normal meat-eater like me ;-).
I also had a couple of problems at first, but there's a quite cool detailed description/PDF https://github.com/pidtuner/pidtuner.github.io/blob/master/assets/doc/PID%20Tuner.pdf you really should download, read and try to understand. It blowed a lot of PID-Tuning fog away for me (after I read it a second or third time ;-)).
At last, I didn't succeed as expected and opened an issue https://github.com/pidtuner/pidtuner.github.io/issues/13 on PID-Tuners Github site. Please check this also!
Both together (the PDF) and PID-Tuner's second answer https://github.com/pidtuner/pidtuner.github.io/issues/13#issuecomment-1321226885 let me succeed at the end.
