Unformatted text preview: (h)(7). Now use to bring down the overshoot, i.e., increase 1 K . With the proportional gain K= 34, find so that 1 K =0.8. (i)(15). Set =0, and draw the root locus as K varies from 1 K . (Note. Root locus refers to a plot of the roots of the closedloop characteristic equation as a constant, say K, varies. Choosing several values of K should give you a good idea of the basic shape of this root locus plot.) (j)(15). Set K =34, and draw the root locus as varies from 1 K . 2(25).
