When the unit step response of a unity feedback control system having forward path transfer function G (s) =80/s(s+18)?
A. Overdamped
B. Critically damped
C. Under damped
D. Un Damped oscillatory
Answer:A
When the unit step response of a unity feedback control system having forward path transfer function G (s) =80/s(s+18)?
A. Overdamped B. Critically damped C. Under damped D. Un Damped oscillatory
Explanation: The open loop transfer function is first converted into the closed loop as unity feedback is used and then value of damping factor is calculated.
