Initial tuning values

[madz468]

Hi,

I have found that using the initial PID tuning values the website provides for the 1st order equation is actually quite accurate for the system I am working on when implemented.

I wanted to know what method the website uses to predict the best PID tuning values are when I first plug in my data?

Thank you!

Hey, happy to hear it worked for you with ease.
As you can imagine, the algorithm is rather complex, but generally speaking, it consists of:

• a series of both linear and nonlinear system identification techniques to identify the models based on your data.
• skogestad’s IMC rules for PID tuning based on the models (https://folk.ntnu.no/skoge/publications/2003/tuningPID/more/tuningpaper_reno-2001/tuningpaper_06nov01.pdf)

The PID tuning rules are just given as a tuning starting point. The valuable information are actually the models, you can use any tuning rules over the models to achieve whatever you want with your PID.

Cheers
