While trying to design a controller for a passive system, I am a bit
confused regarding the problem stated below:

All such functions are written like:
e(s) = Z(s).f(s) where e is effort, and f is flow, for example, a
mechanical system would be described as

F(s) = Z(s).V(s) where F is force, and V is velocity.

I am getting confused that all this is in Laplace domain, what if I were to use this concept in time-domain? How would I translate a hybrid impedance transfer function from Laplace to time? Ofcourse I can take I.Laplace, but I feel I am missing something very basic.. Any help???

Thanks.
