The open-loop transfer function is
given as follows:
K(s + 2.1) (s+ 4.9)4
(s + 6.4)° (s + 7.6)7
G(s)
If s = g is the coordinate where all the
asymptotes (in the corresponding root-
locus diagram) would meet on the real
axis of the s-plane, then what is the
value of 'g'?

In the control system shown by the
above block diagram, the disturbance
is negligible, i.e. D(s) = 0. The transfer
functions G1(s) and G2(s) are as
follows:
3
G1(s)
%3D
4s + 1
1
G1(s)
s2 + 5s + 5
If the error transfer function E(s)/R(s)
of the system is given by
E(s)
R(s)
as3 + bs? + cs + d
4s3 + qs? + rs +p
then what is the value of the constant
"b' ?
