INTRODUCTION
INTRODUCTION
In control and stability theory, Root Locus
analysis is a graphical method for examining
how the roots of a system change with
variation of a certain system parameter,
commonly a gain within a feedback system.
This is a technique used as a stability
criterion in the field of classical control theory
developed by Walter R. Evans which can
determine stability of the system. The Root
Locus plots the poles of the closed loop
transfer function in the complex s-plane as a
function of a gain parameter (see pole–zero
plot).
