The steady state error of a unity feedback linear system for a unit step input is 0.1. The steady state error of the same system, for a pulse input r(t) having a magnitude of 10 and a duration of one second, as shown in the figure is
-
- 0
- 0.1
- 1
- 10
Correct Option: A
| For step input, ess = 0.1 = | ||
| 1 + k |
Now input is pulse r(t) = 10 [u(t) – u(t – 1)]
| R(s) = 10 |  |  | ||
| s |
