Question 3 The results of an open loop frequency response test are presented in Table Q3. (rad/s) 0.1 0.5 1 2 4 7 10 20 50 100 Gain (dB) 40.0 26.0 20.0 14.0 5.0 -3.0 -9.0 -24.0 46.5 -65.5 Phase () -90 -99 -107 -124 -149 -174-192 -221-250 -260 Table Q3 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? d) 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)
