(9) The Bode diagram of the open-loop transfer function G(s) of a unity feedback control system is obtained experimentally and is shown below when its loop gain K is set at its nominal value, Ko. 1. Find the gain and phase margins of the system from the diagram as best you can read. Also find the gain and phase crossover frequencies. Gain crossover frequency @1 =, Phase crossover frequency @2 =, GM = PM = 2. Repeat part (1) if the loop gain K is 10 times its nominal value (i.e., K = 10 Ko). Gain crossover frequency oi = Phase crossover frequency @2 = GM = PM =
