Unformatted text preview: Solution: The part between-2 and 0. (2.5 pts) Find the asymptotes of the root locus (their center and angles) and mark them on the above plot. Solution: There are two asymptotes diverging to innity along 90 angles, with the center [(-2 + j . 5-j . 5)-0] / (3-1) =-1. (2.5 pts) Determine if z = j 2 is on the root locus. If not, what is the angle of deciency ? Solution: The angle of diciency is = 180 -n G ( j 2) =-45 , which is not 0. Therefore, j 2 is not on the root locus. See the plot next page for the root locus by Matlab. 1-3-2-1 1 2 3-2-1.5-1-0.5 0.5 1 1.5 2 2.5 Root Locus Real Axis Imaginary Axis 2...
