Conventionally, we obtain model coefficient values by open-loop step-testing of the process; but this creates undesirable process upsets, and only reveals the local process behavior.  This article suggests that simple phenomenological (first-principles mechanistic) modeling can provide coefficient values, without upsetting the process; and it also reveals how the values change with operating conditions.
