A hydraulic actuated motor has been subjected to a frequency-response test. The data from the test are shown in the following table: w [rad/s] 0.01 0.1 0.3 0.5 1 3 5 10 30 50 100 Magnitude (dB) ● -20 -20.0869 -20.7524 -21.9490 -26.0638 -40.3743 -49.2686 -63.0967 -89.0945 -102.1120 -120.0441 Phase (degrees) -1.2032 -11.9941 -35.1168 -55.9925 -95.7106 -159.8293 -183.9452 -213.5788 -247.7467 -256.3985 -263.1435 If the chosen controller is a proportional one, with kp=20, estimate the following values: Steady state error to a unit step input Gain margin in dB Phase margin in degrees Crossover frequency in rad/s
