Bifurcation and chaos in a phase controlled rectifier-fed dc drive under voltage mode control

This paper explores the nonlinear phenomena like bifurcation and chaos that occur in a phase-controlled rectifier-fed dc drive. It has been shown that depending on the parameters, motor armature current may exhibit several types of evolution in continuous time and so different types of borderline trajectories exist in such system which lead to border collision bifurcation in many cases. These borderlines have been defined and explained.
