The results of an open loop frequency response test are presented in Table Q3. w (rad/s) 0.1 0.5 1 2 4 Gain (dB) 40.0 26.0 20.0 14.0 5.0 Phase () -90 -99 -107 -124 -149 Table Q3 a) Plot the bode diagram for the system (Please see the note on the cover page related to availability and use of graph paper.) b) Evaluate the following terms: i) gain crossover frequency ii) phase crossover frequency iii) gain margin iv) phase margin c) Proportional Control is to be used on the above system to achieve a phase margin of 50°. What value of proportional gain is required? Estimate the system's order and type number. (You are given that a system's type number is equal to the number of integrators it contains in the open loop) Question 3 100 7 10 20 50 -3.0 -9.0 -24.0 -46.5 -65.5 -174-192 -221 -250 -260 (4 marks) (2 marks) (2 marks) (2 marks) (2 marks) (4 marks) (4 marks)
