The transfer function of the system is G(s) =100/(s+1) (s+100). For a unit step input to the system the approximate settling time for 2% criterion is:

The transfer function of the system is G(s) =100/(s+1) (s+100). For a unit step input to the system the approximate settling time for 2% criterion is: Correct Answer 4 sec

G(s) =100/(s+1) (s+100) Taking the dominant pole consideration, S=-100 pole is not taken. G(s)= 100/s+1 Now it is first order system, ts=4T=4 sec.
