A control system which has only feed-forward behavior responds to its control signal in a pre-defined way without responding to how the load reacts; it is in contrast with a system that also has feedback, which adjusts the output to take account of how it affects the load, and how the load itself may vary unpredictably; the load is considered to belong to the external environment of the system.<br /> <br /> In a feed-forward system, the control variable adjustment is not error-based. Instead it is based on knowledge about the process in the form of a mathematical model of the process and knowledge about or measurements of the process disturbances&quot;. For instance such knowledge may be the known inertia (mass) and friction of the system.<br /> <br /> Source Wikipedia: [http://en.wikipedia.org/wiki/Feed_forward_(control) Feed forward (control)]</div>
