Hello Community,
I will be tuning the tension controller. I see it in the Help about controller tuning. In the help it says ‘set line speed to zero and change step’, what does change step mean here.
I need more descriptive information about this controller tuning.
Or what are the things I need to do step by step?
Thank you in advance for your experiences.
Best Regards,
Fatih
Hi,
a step change is a (close to) immediate change between a low (or 0) value to a high value in the setpoint (or vice versa)
The graphic here shows such a step change
As I am not aware of any autotuning methods in MpTension I think this short explanation is referring to manual tuning using such a step change and observing the response manually and setting the parameters.
One example of such tuning would be Ziegler-Nichols - see here: Proportional–integral–derivative controller - Wikipedia
I had quick look for a short tutorial and found this being probably helpful:

Try starting with the values in the boxes and fiddling around with them until you are satisfied with the controller quality.
I hope this helped a little
