non- linear System Identification

$

Hello LabVIEW community,

I have a question for the purpose of a System Identification.
It is a strongly non- linear system based on the magnetostrictive effect. The non-linearity of the magnetostrictive actuator is strongly frequency dependent.

I suspect that the biggest non-linearity is caused by the magnetic hysteresis.

Now my question: Are there any identification models in LabVIEW, which provide me a mathematical model for my problem? This model is designed on the

one hand for the simulation, on the other hand for the compensation of non-linearity.

I heard from a Hammerstein - Wiener model, is it possible for my case to approximate with this model the non-linearities? I think the problem here can be the hysteresis, but i dont know exactly because i have no experience with this model.
I also heard of Volterra filters in combination with a LMS / RLS algorithm. Are these implemented in LabVIEW?
Or are there other possiblities to identify the system by measurment? An analytical solution is not possible for me because I can not physically describe the system.

I would be grateful for any help.

 

Kevin
