In control systems, feedback control works primarily to _______ while feedforward control aims to _______.

In control systems, feedback control is primarily designed to eliminate errors by measuring the output and comparing it to the desired target. When a discrepancy is detected, the system can adjust its inputs accordingly to correct deviations from the desired outcome. This means that feedback mechanisms continually assess performance and work to minimize or eliminate any errors in the system.

On the other hand, feedforward control aims to prevent errors by anticipating changes and acting on them before they affect the output. By analyzing the input variables and assessing how they will influence the system’s behavior, feedforward control allows for proactive adjustments rather than reactive ones. This approach focuses on managing conditions that could lead to errors before they occur, optimizing the process for better performance from the outset.

This division of roles highlights the complementary nature of feedback and feedforward control within systems, with feedback responding to errors that have already occurred, while feedforward aims to prevent such errors in the first place.
