    What will be the closed loop transfer function of a unity feedback control system whose step response is given by
    c(t)=K[1-1.66exp(-8t)sin(6t+37o)]

    a.100K/(s2+16s+100)
    b.10K/(s2+16s+100)
    c.K/(s2+16s+100)
    d.10K/(s2+8s+10)

    Information Re: Clear my doubts

    hi....friend
    i hope the answer for the question u asked is option a.

    here is my view about the question...

    comparing the given step response with the step response of second order system for underdamped case.....
    we will get the values of damping ratio,undamped natural frequency.
    By substituting these values in the standard form of closed loop transfer function of second order system we will get the required closed loop transfer function.

    i am sorry if the answer is wrong.i hope this is the answer.
