Feedforward control is a proactive control mechanism that anticipates problems before they occur. It involves identifying potential issues or deviations in the input stage and taking corrective measures in advance to prevent them from impacting the operations.
For example, in manufacturing, feedforward control can be used to adjust the settings of equipment based on expected changes in input variables, such as temperature or humidity, to ensure optimal production conditions.
