Feed forward (control) - Wikipedia
A feed forward (sometimes written feedforward) is an element or pathway within a control system that passes a controlling signal from a source in its external environment to a load elsewhere in its external environment. This is often a command signal from an external operator. A control … See more With feed-forward or feedforward control, the disturbances are measured and accounted far before they have time to affect the system. In the house example, a feed-forward system may measure the fact that the door is … See more Historically, the use of the term "feedforward" is found in works by Harold S. Black in US patent 1686792 (invented 17 March 1923) and D. M. MacKay as early as 1956.
