Question: P9.24 A closed-loop system with unity feedback has a loop transfer function K(s+30) L(s) = G(s)G(s) = $2 (a) Determine the gain K so that

P9.24 A closed-loop system with unity feedback has a loop transfer function

K(s+30) L(s) = G(s)G(s) = $2 (a) Determine the gain K so

K(s+30) L(s) = G(s)G(s) = $2 (a) Determine the gain K so that the phase margin is P.M. 35. (b) For the gain K selected in part (a) determine the gain margin of the system. (c) Predict the bandwidth of the closed-loop system.
