Consider the unity feedback control system in Figure 5.42 where

K L(s) = Ge(s)G(s) = s(s +5)* The design specifications are: i. Peak time T, 1.0 ii. Percent overshoot P.O. 10%. With K as the design parameter, it follows that a. Both specifications can be satisfied. b. Only the first specification T, = 1.0 can be satisfied. c. Only the second specification P.O. d. Neither specification can be satisfied. 10% can be satisfied.
