Hello,
I have to find the transfer function of a given model (matlab). My task is to determine this function, by means of a step response of the system. I have to use graphical methods tot get the parameters, the proces itself is a high order proces with non minimum phase.
[tex]G(s)=K.\frac{(1-Ts)}{(1-\tau s)^{n}}[/tex]
My first attempt (the blue curve isn't very accurate. Someone whith experience who can help me out?
To situate my problem: I have have to find the proces-parameters witch graphical data. Problem is, this isn't very accurate at all..So I'm kinda gambling...But is what I wrote down correct for this process?
Aprreciate help!
grtz
