Stability Analysis of Controlled DC Motor
Article Sidebar
Main Article Content
Abstract
Controlled dc motors are nonlinear systems, that
show a nonlinear action in their operation including, sub-
harmonics and chaos when they work outside their design
specifications. This nonlinearity forces the motor changing
its normal operation to a random-like behaviour; In this
paper, the nonlinear dynamics of DC motors are
investigated. It is shown that the concept of the Poincaré
map approach and the monodromy matrix method can be
successfully applied to determine the stability of DC motors
