Bode plot of under damped system Resonant Peak at 5 rad/sec Natural oscillating frequency of system 90 degree phase shift at resonant frequency . WebThe blue graph (in which the second order poles are assumed to dominate) is obviously a bad approximation and not useful, as expected. Frequency Domain: The magenta (exact) and red (due to pole at 0.1 rad/sec) Bode plots are very close until the frequency is between 1 and 10 rad/sec.
WebMagnitude plots for underdamped second order systems are difficult and there is no obvious way to do so. This document presents two methods, either of which is … WebRecall that for a second order system of the form ω n 2 (jω) 2 +2ξωn(jω)+ω n 2 , the system is underdamped if ξ ∈ (0, 1), overdamped if ξ > 1 and critically damped if ξ = 1.
