What is feed forward control? Feed forward applies a corrective action from measured disturbances before the controlled variable deviates.
Feedback vs Feed Forward: Feedback reacts to steam temperature error after deviation; feed forward anticipates based on inlet flow and inlet water temperature.
Why useful: Better disturbance rejection, less oscillation, tighter steam temperature control.
Typical use: Boilers, fired heaters, furnaces, heat exchangers, and blending systems.
