$($a$)$ Use sisotool to build the root locus for a proportional

controller. Overlay the given design requirements to show

that a proportional controller is not feasible.

$($b$)$ Use the sisotool to determine the gains for a PD

controller.

G$($s$)$ is the position transfer function derived earlier. Aim

for $0\%$ overshoot by just getting the poles on the real axis.

Choose a zero location that produces an integer term in

C$($s$)$ equation. Likewise choose an integer value for the

gain
