概周期激励Lozi系统的奇异非混沌吸引子分析
Analysis of Strange Nonchaotic Attractors in Quasiperiodically Forced Lozi System
摘要
Abstract
Numerical simulation was used to explore the strange nonchaotic attractor and dynamic characteristics of the Lozi system under quasiperiodically drive.The results show that with the change of system parameters,the system gradually evolves from a non-smooth torus to a strange nonchaotic attractor with a fractal architecture.The existence of the strange nonchaotic attractor is verified by the calculation of the maximum Lyapunov index and the phase sensitivity exponent.The characteristics of strange nonchaotic attract-ors were analyzed in detail using methods such as power spectra,local Lyapunov expo-nents distribution and recurrence plots.The rational approximation of the Fibonacci se-quence was used to further reveal the formation process of the strange nonchaotic attract-or.关键词
