WebBoth feedforward and feedback control of many body functions are performed without any conscious effort. This is achieved by a part of the nervous system called the autonomous … WebAbstract. Tremor is defined as rhythmic oscillatory activity of body parts. Four physiological basic mechanisms for such oscillatory activity have been described: mechanical oscillations; oscillations based on reflexes; oscillations due to central neuronal pacemakers; and oscillations because of disturbed feedforward or feedback loops.

Web14.4.9.1 Feedforward Control. Feedforward control differs from feedback control in that the load or primary disturbance is measured and the manipulated variable is adjusted so that deviations in the controlled variable from the setpoint are minimized. The controller can then reject disturbances before they affect the controlled variable. 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 b… WebJames P. Fisher (1), Niels H. Secher (2) and Paul J.
