For a unit step input, a system with forward path transfer function G(s) = 20 s2
and feedback path transfer function H (s) = (s + 5), has a steady state output of_______
-
- 7.2
- 0.01
- 0.002
- 0.2
Correct Option: D
| C(s) = | R(s) | |
| 1 + G(s) H(s) |
(Assuming negative feedback)
| C(s) = | ||||||
| s2 | = | |||||
| 1 + |  |  | (s + 5) | s2 + 11s | ||
| s2 | ||||||
| G(s) = | ||
| s2 + 20(s + 5) |
