engineering recuitment GATE IN Test Series 2023-24 Mock Test Control Systems Frequency Response Analysis
The magnitude of the frequency response of a second order closed loop system with transfer function \(\frac{{C\left( s \right)}}{{R\left( s \right)}} = \frac{4}{{{s^2} + s + 4}}\) is shown below.
The resonant frequency ω0 and the resonant peak M0 are
1
ω0 = 0.66 rad/sec, M0 = 6.30 dB
2
ω0 = 0.66 rad/sec, M0 = 12.30 dB
3
ω0 = 1.87 rad/sec, M0 = 12.30 dB
4
ω0 = 1.87 rad/sec, M0 = 6.30 dB
