Expert System and Model-Based Self-Tuning Controllersows through its tube bundle. A simple control scheme senses the outlet water temperature and attempts to position the steam valve so that the actual water temperature equals the desired water temperature. Effects of both nonlinearities in the steam valve and changing steam pressure can be reduced by
