Study on the Fractal of Chaotic Boost Circuit Based on Multi-scale Analysis

摘要

The fractal parameter is very import in studying the chaos signal. Wavelet transform is a useful multi-scale tool for analyzing the fractal. In this paper, we discuss the self-similarity property of chaos signal and the properties of the coefficient of wavelet transform in different scales, and study the signal of dc-dc circuit in chaotic state by wavelet transform. From deduction, we get the algorithm of calculating the fractal parameter of the chaotic attractor of the circuit. At the end of the paper, we do the calculation and simulation.
