For the following open loop transfer function

$G(s)=\frac{K}{s(s+6)}$

design a PD controller $K_p+K_{D}S$ such that the unity closed$-$loop system satisfies the following specifications $($In the above $G(s),$ please let $K=8)$

$($a$)$ Steady$-$state error with a unit ramp input less than or equal to $0\mathrm{.}01$

$($b$)$ Overshoot $\%$OS less than or equal to $8\%.$

$($c$)($You don't need to verify $T_r$ and $T_s)$
