Problem 1
:
(a)
Prove the root locus consists of
n
branches which start at the
n
poles of the open loop system
and approach the zeroes of the open loop system a
K
varies from 0 to ∞.
(b)
For the system H(s), find the location(s) of the break away and break in points, if any, on the
real axis.
?(𝑠) =
1
(𝑠 + 2)(𝑠 + 7)(𝑠 + 13)
Problem 2:
For the system G(s) given below, design a lead controller in the s-domain to give less than 10
