Question

Consider the non-unity feedback system in Figure E8.14, where the controller gain is K = 2. Sketch the Bode plot of the loop transfer function. Determine the phase of the loop transfer function when the magnitude 20 logi|L(jω)| = 0 dB. Recall that the loop transfer function is L(s) = G_c(s)G(s)H(s).
