1. Feed-forward is a term describing a kind of system which reacts to changes in its environment, usually to maintain some desired state of the system. A system which exhibits feed-forward behavior responds to a measured disturbance in a pre-defined way - in contrast with a feedback system.

2. This is a control technique that can be measured but not controlled. The disturbance is measured and fed forward to an earlier part of the control loop so that corrective action can be initiated in advance of the disturbance having an adverse effect on the system response.

Feed Forward control is mechanism within some control systems in which information is sent ahead in time to prepare a part of a control system.

Feedforward feedback control?

Feedforward is a preparatory control. EX. Smelling food leads to salivation and production of stomach acid in preparation of food. OR Starting to exercise increases heart rate and breathing rate in preparation of running low on oxygen for muscles. Feedback is a control mechanism where the product of the end mechanism either enhances or inhibits the start of the mechanism Positive feedback enhances Negative feedback inhibits


What is the Advantage and disadvantage of feedforward control?

One major advantage of feedforward controls is that it prevents large disturbances in your output. A disadvantage is that it may not account for all potential disturbances in the input, leading to large disturbances in the output.

What is the basic control process?

It begins with the establishment of clear standards of performance, involves a comparison of performance to those standards, takes corrective actions, if needed, to repair performance deficiencies; is a dynamic, cybernetic process, and uses three basic methods-- feedback control, concurrent control, feedforward control.


Why do you prefer feedforward control?

Feedforward is anticipatory in nature. It is your body preparing for something before it occurs. The classic example is smelling something delicious. Even though you haven't eaten anything yet, your mouth begins to salivate, excreting digestive enzymes, and your stomach begins to produce acid. This way your body doesn't have to quickly react. Another example is exercise. Your heart rate and breathing rate increase long before your muscles begin to run low on oxygen. You can almost think of feedforward as a type of preventative measure.
