In physiology, feed-forward control is exemplified by the normal anticipatory regulation of heartbeat in advance of actual physical exertion by the central autonomic network. Feed-forward control can be likened to learned anticipatory responses to known cues (predictive coding). Feedback regulation of the heartbeat provides further adaptiveness to the running eventualities of physical exertion. Feedforward systems are also found in biological control of other variables by … WebJan 21, 2011 · Only two core topologies emerged: a negative-feedback loop with a buffering node and an incoherent feedforward loop with a proportioner node.
