Hi you made a great job!!!

I would like to ask you about puting the parametres of pid.Specifically, do you put them costantly? Or you have colculated ?

"I try to find the mathematical model of this system and colculate the pid parametres."

Thank you

Hi,

I did a pratical evaluation of the parameters.
First I adopted a "P" value and after I increased the "I" value till get oscillation and then I decreased it in order to not have oscillation. I let the "D" value as zero.
