E5.20 Consider the closed-loop system in Figure E5.20, where

L(s) = (s + 2) (s+5s) -Ka-

(a) Determine the closed-loop transfer function T1s2 = Y1s2>R1s2.

(b) Determine the steady-state error of the closedloop system response to a unit ramp input.

(c) Select a value for Ka so that the steady-state error of the system response to a unit step input is zero.
