10 GH = 60 B) For the system shown in 6A calculate the magnitude and phase of response for a unit...
please show steps 5. GH(s) is a minimum-phase system which has the Bode plot shown below. It is desired to increase the phase margin by 40 degrees and also increase the closed-loop system bandwidth. Design a lead compensator for this purpose. Determine (1) the ratio of the pole to the zero, α , (2) the frequency where the maximum phase shift from the compensator should be placed, and then (3) the pole and zero. You need not draw the Bode...
The Bode plots for a plant, G(s), used in a unity feedback system are shown in Figure P10.7. Do the following: Find the gain margin, phase margin, zero dB frequency, 180° frequency, and the closed-loop bandwidth. Use your results in Part a to estimate the damping ratio, percent overshoot, settling time, and peak time. ANSWERS GIVEN BY PROFESSOR 1. Gain margin = 20dB, Phase margin = 55 deg, Zero dB frequency = 1rad/s, 180deg frequency = 4.5rad/s, bandwidth (-7dB) closed-loop...
