Please see the image also where the PID values can be seen.
Thank You

Hi Aruvi,
PID controls are made for linear systems. When your system acts nonlinear you need to use a different control algorithm - or adapt your PID to use different PID parameters depending on system workpoint!
In the PID toolkit you will find a GainSchedule function that helps you in this matter…
And PLEASE put more text in the message body and (much) less in the topic title!

How did you choose your PID tuning values? Did you go through one of the standard PID tuning methods? If you do not do a full tuning of the PID loop, you are unlikely to get stable performance. It is difficult to tune a PID loop properly through trial and error.

@GerdW
Thank You...... 🙂
But didn't you notice that the other set points are achieved properly, but zero wasn't. Tha fact is that we have to go to the negative side also.... what to do?

@nathand
Thanks for the reply...
I am using this PID logic for the first time. Do you have any link to learn tuning PID parameters?
