5. Sketch the root locus for L(s) =
s+10
using rules 1, 2, and 4. For rule 4, you need to
s(s+6)
find the break-in and break-away points.
S+4
4. Sketch the root locus for L(s) = (s+6) (s+1)2 using rules 1, 2, and 3. For rule 3, you
need to find the value of σ and a for the asymptotes.
From the root-locus, explain why the closed-loop system is always stable for any
choice of the design parameter K in the range 0 < K < ∞o.
2. Consider the following system.
K(s+3) (s+4)
(s+1)(s+2)
Check whether the points below are in the root locus. If the point is in the root locus, then
also find what the corresponding gain K.

-2+1√ √
Hint: First find L(s). Next, in L(s) replace s with the value of the point and then express
it in polar format r20 using calculator. The point will be in the root locus if and only if
= 180° or odd multiple of 180°. When the point is in the root locus, the
corresponding gain K is obtained as K ==
