A feed forward (sometimes written feedforward) is an element or pathway within a control system that passes a controlling signal from a source in its external environment to a load elsewhere in its external environment. This is often a command signal from an external operator.
Feedforward control addresses this weakness by taking a fundamentally different approach, basing final control decisions on the states of load variables rather than the process variable. In other words, a feedforward control system monitors the factor(s) influencing a process and decides how to compensate ahead of time before the process ...
This article aims to define what feedforward control means, provide examples to illustrate its application, discuss its key characteristics, and highlight its significance in organizational management.
Apr 1, 2019 · Feedforward control can operate faster and preemptively and doesn’t need to wait for the results of past control efforts. Effective feedforward control measures upcoming disturbances and accurately predicts what effects they’re about to have on the process variable.
Feedforward control is a proactive control strategy that anticipates disturbances by measuring input variables before they affect the output of a system. This method allows for adjustments to be made based on known or predicted changes, thereby improving the system's responsiveness and stability.
Mar 11, 2023 · Feed-forward control will compensate for fluid input disturbances while feedback control will compensate for other disturbances—such as the fuel gas flow rate or the temperature of the furnace—and model uncertainty.
Feedforward control is a proactive mechanism used in motor control that anticipates the necessary actions required to achieve a desired outcome. This system relies on pre-existing knowledge and sensory information to adjust movements before they are executed, rather than relying solely on feedback after the action has taken place.
