+ For a unity feedback system with open-loop transfer function given by: K G(s) s(s+1)(8 +5) (i) Obtain the characteristic equation of the closed-loop system and the range of stability for K values using the Routh array (6 Points) Sketch the root locus of G(s) as K varies from 0 to + infinity, determine the asymptotes, centroid (point on the real axis where the asymptotes meet) and, breakaway point. (9 points) (iii) By substituting s - jd in the characteristic equation obtain the frequency of oscillations for the value of K for which the root locus crosses the imaginary axis. (5 points)
