8. A second order lag process has a resonant frequency, (o, of 10 rad/sec, a damping ratio of 0.1, and a steady state gain, G, of 1. Use the Bode diagram in figure given to determine the gain, m,...
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...
