11
The bode plot is a standard approach to feedback control systems
analysis and design. The transfer function of a second-order
system is given by
G (s) =
(s+a)
(s+b)(s+c)(s+d)
Here s = jw, where w is the frequency and a=0.74, b=2.48,
c=8.81 and d=1.93 are real constants. Bode plot requires the
calculation of amplitude and phase at certain frequencies and
plotting them in two separate graphs. Calculate the amplitude of
the Bode plot at the corner frequency w = b =2.48 rad/s.
