Unformatted text preview: Solution: The part between2 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 in±nity along ± 90 ◦ angles, with the center [(2 + j . 5j . 5)0] / (31) =1. (2.5 pts) Determine if z = j 2 is on the root locus. If not, what is the angle of de±ciency φ ? Solution: The angle of di±ciency is φ = 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. 1321 1 2 321.510.5 0.5 1 1.5 2 2.5 Root Locus Real Axis Imaginary Axis 2...
