DRILL PROBLEMS D4.6 Sketch root locus plots for the systems in Figure D4.6. Find asymptotic angles, centroid, approximate breakaway points, angles of departure, and angles of approach where applicable. Ans. (a) ±60°, -180°; -; none; 18°; none; (b) ±90°; -20; -15.3; none; none; (c) ±90°; -6; -6.87; none, none; (d) +60°, --180°; -; none; +33.7; none. D4.7 For systems with the root locus plots shown in Figure D4.7, find the value of the adjustable constant K for which the overall transfer function has a pole at the location indicated by the dot. Ans. (a) K = 1.4; (b) K = 2; (c) K = 1000
