feedforward control

feedforward control

an anticipatory correction in motor behavior. During movement, various brain centers depend on feedback from receptors to control motor behavior. If the actual and intended motor behaviors do not match, an error signal is generated and alterations are made. In some instances the control system anticipates an error and makes the corrective change in advance of the start of movement.
