Hi,
I want to set a PID from "PID tuner". It seems like it is not possible to set a normal PID from PID tuner, it requires the "N" term. My concern is I don't want the to add the N term in my PID.
Does anyone can tell me what is the procedure to do not take into acount the "N" term from PID tuner?
Thanks in advance

You cannot choose PID without derivative filter in the PID Controller block.
If you need PID without a filter:
1) Use transfer function block as your controller
2) Add input and output linearization points to your model
3) Tools-control design-compensator design
4) select your controller transfer function as the block to tune
5) Go to automated tuning tab, select PID tuning, choose PID, press update compensator.

Your transfer function block is now a PID controller with no derivative filter.
HTH.
