Question
Given a unity feedback system with
1
G(s):
=
(s+1.1)(s+1.8) (s+7.9)
Draw the root locus of the system.
A proportional controller with gain Kp is inserted before the plant. Find the value of Kp that gives
a damping ratio equal to 0.15.
Specify a value of Kp that is a multiple of 5. Try your best to find the roots that will yield a 7 that
is very close to 0.15.
Answer:
Instead of a P controller, a PI controller is inserted to also improve the steady-state error of the
system.
The Pl controller has a zero at -0.2. If the transfer function of the controller is of the form
s+0.2
S
Gc(s) = Kp.
what is the value of Kp that will yield a damping ratio close to 0.15 for the compensated
system? Specify a value of Kp that is a multiple of 5.
