SOLVED: Draw the root locus on graph paper for all the four closed-loop systems given below. For each, find the dominant poles with damping ratio ζ = 0.5 and the value of K which gives this value of ζ. R(s) = K(s^2 + 2s) / (s + 3) C(s) = (s^2 + 4s + 5) / (s + 3) Figure 1 for ζ = 0.1 R(s) = K(s + 3) / (s^2 + 10s + 20) C(s) = (s^2 + 8s + 18) / (s + 2) Figure 2 for ζ = 0.2 R(s) = K(s + 3) / (s^2 + 8s + 18) C(s) = (s^2 + 10s + 24) / (s + 4) Figure 3 f
