Section B Question 2 explain Steps Please A level control system with open loop transfer function g(s) = 0.5 s(s + 1) 4 proportional controller with added lag term', k(s), where k(s) == (s+1) is controlled using a ارسی | (i) Using the frequency response theorem, develop expressions for the open loop gain and open loop phase for the level control system in series with the controller. . [7 marks] (ii) Show that when the angular frequency is 1rad/s, the open loop gain is 0dB. [3 marks] (iii) how?? Draw the Bode diagram for the open loop system.
