In this paper, the fractional-order Genesio--Tesi system showing chaoticbehaviours is introduced, and the corresponding one in an integer-order formis studied intensively. Based on the harmonic balance principle, which iswidely used in the frequency analysis of nonlinear control systems, atheoretical approach is used to investigate the conditions of systemparameters under which this fractional-order system can give rise to achaotic attractor. Finally, the numerical simulation is used to verify thevalidity of the theoretical results. 相似文献

A novel chaos communication method is proposed based on synchronization of discrete-time chaotic systems. This method uses a full-order state observer to achieve synchronization and secure communication between the transmitter and the receiver. Further, we present a multiple-access chaotic digital communication method by combining the observer with the on-line least square method. Simulation results are also given for illustration. 相似文献

下载免费PDF全文 A new chaotification method is proposed for making an arbitrarily given discrete Takagi-Sugeno (TS) fuzzy system chaotic. Based on a given discrete TS fuzzy system, the new chaotification method uses the decentralized state-feedback control and the continuous sawtooth function, instead of the modulo operation, to construct a chaotic nonlinear system,which can generate discrete chaos with the arbitrarily desired amplitude bound. We apply the improved Marotto theorem to mathematically prove that the controlled system is chaotic in the sense of Li and Yorke. In particular, an explicit formula for the computation of chaotification parameters is obtained. A numerical example is used to illustrate the theoretical results. 相似文献

This paper proposes a new, simple and yet applicable output feedbacksynchronization theorem for a large class of chaotic systems. We take alinear combination of drive system state variables as a scale-drivingsignal. It is proved that synchronization between the drive and the responsesystems can be obtained via a simple linear output error feedback control.The linear feedback gain is a function of a free parameter. The approach isillustrated using the R\"{o}ssler hyperchaotic systems and Chua's chaoticoscillators. 相似文献

In this paper we numerically investigate the chaoticbehaviours of the fractional-order Ikeda delay system. The results showthat chaosexists in the fractional-order Ikeda delay system with order less than 1.The lowest order for chaos to be able to appear in this system is foundto be 0.1. Master--slavesynchronization of chaotic fractional-order Ikeda delay systems with linearcoupling is also studied. 相似文献

In this paper, an approach for chaotifying a stable controllablelinear system via single input state-feedback is presented. Theoverflow function of the system states is designed as thefeedback controller, which can make the fixed point of theclosed-loop system to be a snap-back repeller, thereby yieldschaotic dynamics. Based on the Marotto theorem, it provestheoretically that the closed-loop system is chaotic in thesense of Li and Yorke. Finally, the simulation results are usedto illustrate the effectiveness of the proposed method. 相似文献

研究了利用任意小幅值的状态反馈控制来混沌化稳定的Takagi-Sugeno (TS) 模糊系统问题。所用状态反馈控制器是系统状态的锯齿函数。我们应用改进的Marotto定理从数学上证明了受控系统在Li-Yorke意义下是混沌的。特别地,给出了计算混沌化参数的解析公式。最后一个数值例子被用来说明所提的理论结果。 相似文献

研究了利用分散状态反馈控制使稳定的Takagi-Sugeno(TS)模糊系统产生Devaney混沌的问题。所提的分散反馈控制器是由分散线性反馈控制器与2补运算的溢出非线性函数复合而成的。2补运算的溢出非线性导致了复杂动态。应用Shi-Chen定理从数学上证明了受控系统在Devaney意义下确实是混沌的。给出了计算混沌化参数的解析公式。一个数值例子被用来说明所提的理论结果。 相似文献
