Chaotic systems have been shown to have interesting properties for the generation of spreading sequences in various spread-spectrum applications. The aim of this paper is to exploit the topological features of a time-delay system with appropriate non-linearity to propose sequences having good correlation properties. A novel family of chaotic sequences is proposed as spreading sequences using the Poincare...
The dynamic behavior and stability analysis of a quadratic boost converter for high conversion ratio applications is addressed. After studying the stability of the system by using the monodromy matrix, a closed form stability condition is used for predicting the boundary of subharmonic oscillation in the system in terms of the duty cycle and the slope of the ramp modulator. The derived theoretical...
In this paper, we explore some modeling capabilities of Scicos. Our aim is to generate chaos from a simple hybrid dynamical system. We give the chaotic dynamics of the current-programmed boost converter in open-loop circuit as a case study. By considering two bifurcation parameters the current reference and the voltage input, we observe that the obtained Scicos simulations show that the boost converter...
