Given a unity feedback control system with G (s) = K/s(s+4), the value of K for which the damping ratio is 0.5.
A. 1
B. 16
C. 64
D. 32
Answer:B
Given a unity feedback control system with G (s) = K/s(s+4), the value of K for which the damping ratio is 0.5.
A. 1 B. 16 C. 64 D. 32
Explanation: The value is found by using the Routh- Hurwitz criteria and equating one of the row of the Routh-Hurwitz criteria equal to zero and hence finding the value of K.
