Process Reaction Curve: Ziegler-Nichols rules

Is there a Matlab module that includes process reaction curves and Ziegler-Nichols rules??

Thank you for any suggestions. AA

I’m not certain that I understand what you’re asking.

See if the System Identification Toolbox procest function will do what you want.

My pleasure.

I’m not certain what a ‘process reaction curve’ is. Can you provide a relevant reeference?

If what I suggested isn’t what you intend, consider the step function.

Don’t delete it, just edit it to provide a more precise statement of the problem you want to solve.

I generally do state-space control systems, so I was not initially aware that this even existed.

There is Design Compensator Using Automated Tuning Methods, a 10-year-old File Exchange contribution that seems to be reasonably well-regarded: Automated Ziegler Nicholas PID Tuning, and Learning PID Tuning I: Process Reaction Curve that by its format, appears to be relatively old. One Accepted Answer that relates is PID Tuning via Ziegler Nichols Method. There may be more. (I stopped with these.)
