Question:
This problem is based on the solution in Problem 8.4-3. Suppose that in Fig. P8.4-3, the sensor gain \(H=0.04\) is moved back to the feedback path. What effect does this have on the percent steady-state error of Problem 8.4-3, where this error is defined as
\[
\text { steady-state error }=\frac{\text { commanded output }- \text { actual output }}{\text { commanded output }} \times 100
\]
Note that this result allows us to convert a nonunity feedback gain system to a unity-gain feedback system, without affecting the percentage steady-state error.
