Show Hint
\[
\boxed{
\begin{aligned}
\text{Feedback control} &\rightarrow \text{Acts after an error occurs}
\text{Feed-forward control} &\rightarrow \text{Acts before the disturbance affects the output}
\end{aligned}
}

- Reacting after error occurs
- Eliminating sensors
- Compensating disturbances before they affect output
- Increasing gain
Show Solution

The Correct Option is C
Solution and Explanation
Step 1: Recall the principle of feed-forward control.
Feed-forward control measures disturbances and compensates for them before they influence the system output.
Step 2: Identify the correct statement. Unlike feedback control, feed-forward action does not wait for an error to occur. Hence, \[ \boxed{\text{Compensating disturbances before they affect the output}} \] is the correct answer. Therefore, \[ \boxed{(C)} \] is the correct answer.
