I created a Process Model with System Identificaion Toolbox and received a PT2 Transfer function with delay. I exported it to Matlab and received an idproc Model. Now, I wanted to do a Nyquist plot with it, which didn't work. I know that it probably will work if I extract the parameters and build a transfer function with it by myself. I wanna know if it's also working with the idproc element or if there is a fast command to build a transfer function with it.
Thanks in Advance!
