A servomechanism has an open loop transfer function of
G(s) = 10 / s (1+0.5s) (1+0.1s)
Draw the Bode plot and determine the phase and gain margin. A networks having the transfer function (1+0.23s)/(1+0.023s) is now introduced in tandem. Determine the new gain and phase margins. Comment upon the improvement in system response caused by the network
