Consider the systems with following open loop transfer functions

1. 23-203-1

2. 23-203-2

3. 23-203-3

If unity feedback is used, the increasing order of time taken for unit step response to settle is

Answer: Option C

Explanation:

42-203 For the three systems the values of ξω_n are 1.8, 2.5 and 2 respectively.

Hence values of T are 0.55, 0.4 and 0.5 respectively.
