The loop transfer function of a unity negative feedback system K L(s) = G(s)G(s) s(s + 2) A system response to a step input is specified as follows: T, = 1.1 s, 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 time and percent overshoot specifications are relaxed by the same percentage.
pleasee give me clear solution!
