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

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
