I recorded step response of temperature system. I would like to
determent parameters of PI controller for that system.
I work in Matlab so I need hep on next topics:
1. recorded curve is not smooth, can I use LSQR function (or something
else) to make it smooth. I recorded values of temperature in vector
named "heat" and time in vector named "time". Dimensions of vectors are
1 x m.
2. How can I drown tangent for determining of time delay and time const
of system on base of step response. How to do it in Matlab.
3. I would like to make my function for determining of parameters for
PI controller. Function should be based on step response of system in
open loop. Give me advise what my function should look like, what
should include, what useful matlab function should I use.
I'm electrical engineer and this days I'm working on my exam for post
graduated studies, so any help would be useful.
Looking forward to hearing from you. Best Regards.
