underdamped process model

I am estimating the relation between skin temperature and perceived pain, and thus I want to estimate a transfer function. It appears the an underdamped process model with two poles, a delay and a zero provides a good fit (except for some nonlinearities that I can't really model). However, I kind of lack some information to which paper and theoretical background the transfer function structure is build.

best regards Carsten
