The transfer function of a 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:
A. 100 sec
B. 4 sec
C. 1 sec
D. 0.01 sec
Answer:B
The transfer function of a 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:
A. 100 sec B. 4 sec C. 1 sec D. 0.01 sec
Explanation: Comparing the equation with the characteristic equation and then finding the value of G and w and calculating the value of settling time as 4 sec from 4/Gw.
