Asking for Help: a fractional form of implementation

[xiberJ]

Dear developers hello. I want to ask how do terminating forms expand into polynomials

You will need to use an approximation for modeling the above. You can easily compute the frequency domain characteristics of this and then use frequency domain identification tools in FOMCON such as fotfrid for which you just need to prepare a ffidata object from the computed frequency domain characteristics.
