A viable phase-lag compensator for a unity negative feedback system with plant transfer function

1000 G(s) = (s+8)(s+14) (s + 20) that satisfies the design specifications: (i) percent overshoot P.O. 5%; (ii) rise time T, 20 s, and (iii) position error constant K, > 6, is which of the following: a. Ge(s) = s+1 s + 0.074 b. Ge(s) = c. Ge(s) = d. Ge(s) s + 0.074 s+1 20s +1 100s +1 = 20
