I am new to System Identification toolbox. I am currently working on a project where i have experimentally obtained the frequency response of my system. Currently i have to identify a mathematical model that closely matches to the experimentally obtained response. My experimental data is in a FRD model. I use pem command, but the resultant system was not a close match. many of the resonance modes had been clipped off. can someone explain me a much better methodology to arrive at the solution
