Hello,

I'd like know if there is any function to implement an adaptive pid, I program with portal Tia, my plc is an S7-300, Siemens has some function to do this ?, you guys have any example to do this?

Thank you, so much.

Hi,

perhaps this?

Hi,

Thank you for your answer Towome, but I think that the sample of your answer is for self tuning and I need a pid adaptive, I need that P, I, D, values, change in process, and change if the control conditions change, then I think then sample is not good for my system.

Thank you so much.

 The whole available control packages for S7-300,Integrally in TIA , are in form of conventional PID blocks.Perhaps, inside those blocks , several techniques related to different sections of control engineering have been utilized but at the end it is a PID or a tuner as a whole.For more advanced control option , you should try PCS 7 or develop your own algorithm in SCL.

You also have the chance to check the open source libraries such as oscat for some ideas (I guess).

I hope this helps,

When you ask for "adaptive PID", first have a look to "control range" option of the PID blocks.
