Root locus. U(s) C(8) G(8) Y(8) s+4 G(s) s(s+2) Use graphical evaluation of the transfer function to solve this problem. (a) If C(s) = K, does the root locus pass through the point si = -4+jVE? If so, find the value of K that puts a closed loop pole at si. (b) If C(s) = K, does the root locus pass through the point $2 = -4 + j2? If not, calculate the angle deficiency. (c) If C(s) = K(s+b), is it possible to choose a b such that the root locus passes through the point $2 = -4+j2? If so, find the value of b and K that puts a closed loop pole at $2. a
