There may be a small difference between your predicted heater level in Q4 and the simulated heater level in Q5 needed to regulate the system output at 40 degrees C?

Consider
the following three potential reasons why you may observe such a difference.

i. The model (1) used for prediction is an oversimplification, and does not fully
reflect the mildly non-linear relationship between the steady-state input value
and the steady-state output value.

ii. The system response over 600 seconds does not quite reach steady state introducing a systematic error in our estimation of C , and hence our prediction of H .

iii. Since the system temperature starts at the room temperature, rather than at
zero, the model (1) does not make sense.

Which of the following is correct?
