3) Consider the closed-loop control system shown in figure.Compute the steady-state errors for the different values of K-5, K=50: R(s) K X (s) 4) For a unity feedback system with open loop transfer function 9 G(s)=- s(s+2) Calculate The damping ratio and natural frequency 4 s + 10 5)Determine the overall transfer function for a control system in figure below. Input Output 2 S+2 4 Y(s) Y (s) Note: W, = m L[f(t)] = sF(s) - sf (0) - f (0)
