The loop transfer function of a unity negative feedback system (see Figure E5.11) is

A system response to a step input is specified as follows:
peak time Tp = 1.1 s,
percent overshoot P.O. = 5%.
(a) Determine whether both specifications can be met simultaneously.
(b) If the specifications cannot be met simultaneously, determine a compromise value for K so that the peak tune and percent overshoot specifications are relaxed by the same percentage.
