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.
