Thread Subject: How to tune electrical model parameters to match impedance vs frequency measurement

Hi!
I have a plant, of which the parameter being studied is the electrical impedance. I have thus measured the impedance in the frequency range, 100-10000Hz (more specifically: logspace(2, 4, 401) Hz), which is saved in two different vectors (one for the magnitude and one for the phase).

I have then a simple model of an electric circuit in simpowersystems that consists of three capacitors, two inductors and three resistors, whose values I need to tune in order to match the electrical impedance graph that I mentioned before.

I do not have access to the time signals, but only to the above mentioned graph (and vectors) of impedance vs logarithmically-spaced frequency.

I have tried to tune all 8 parameters manually, and checking the effect of the changes with the "impedance measurement" block, but this is taking forever. I need a better/faster way of doing this as the deadline is approaching and I haven't met the requirements.
Please, please help me.

Is there a "tuning" tool that doesn't require time-based signals? Should I switch from simpowersystems to simscape or some other toolbox? Can you point me in the right direction?

Thanks for your time and help, I really appreciate it.
