I am attempting to use era() to idetify a state space realization of my system and validate it using the compare() function. The system I am trying to identify is a steel cube with a heater attached to one side. The system starts at a state state of 0C and then heater applies an impulse flux to distrube the system.

When I use the compare() function to validate my system I see a good fit, but weird initial conditons. I am exspecting the inital conditons to be equal to 0 since all the data starts from steady state = 0C, however the compare() function estimates non-zeros initial conditions. Why is this happening?
Attached is my code and estiamtion / validation data sets.
