    Unity Feedback Control System : Closed-Loop Transfer and Open-Loop Transfer Functions

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Consider a unity-feedback control system with the closed loop transfer function:

    C(s)/R(s) = Ks+b/s^2+as+b

    Determine the open loop transfer function G(s).
    Show that the steady-state error in the unit-ramp response is given by:

    e_ss = 1/K_v = a-K/b
