S(S+1)(S+2)
a. Evaluate the steady-state error for a unit ramp input.
b. Design a lag compensator to improve the steady-state error by a factor of
10(increase the static velocity error constant Kv to about 10 times) to get a new
dominant closed-loop poles. s=-0.3± j0.55. place the zero of the lag compensator
at s=-0.05
