摘要

摘要研究了仅测量输出变量的严格不同模型超混沌系统的同步问题。研究了在已知系统参数和/或完全了解待同步系统的情况下，严格不同系统的同步问题。在假设只有输出系统状态可用于反馈的情况下，给出了超混沌系统的同步问题。控制器主要抵消参数不确定性和矢量场之间差异的影响。控制动作由线性化控制律和高增益状态估计器给出，使两个超混沌系统同步。利用Rössler和Chen超混沌系统的数值模拟证实了结果。

Synchronization of Strictly Different Hyperchaotic Systems with Uncertain Parameters and Models

Abstract The synchronization of hyperchaotic systems with strictly different models measuring only output variables is presented. The synchronization of strictly different systems has been studied assuming the knowledge of the system parameters and/or the full knowledge of the systems to be synchronized. Here the synchronization of hyperchaotic systems is presented assuming that only the output system states are available for feedback. The controllers mainly counteract the effect of parametric uncertainties and differences between vector fields. The control actions are given by linearizing control laws and high gain state estimators, in such manner that both hyperchaotic systems are synchronous. Numerical simulation using the Rössler and Chen hyperchaotic systems is used to corroborate the results.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
