A systematic design process of adaptive synchronization and parameter identification of an uncertain Chen chaotic system is provided.With this new and effective method,parameter identification and synchronization of the Chen system,with all the system parameters unknown,can be achieved simultaneously.Theoretical proof and numerical simulation demonstrate the effectiveness and feasibility of the proposed method. 相似文献

A novel tracking control and synchronization method is proposed based upon sampled-data feedback.This method can make a chaotic system approach any desired smooth orbit and synchronize the driving system and the response system,both in the same structure and in diverse structures.Finally,a numerical simulation with a Lorenz system is provided for the purpose of illustration and verification. 相似文献

Synchronization of a noise-perturbed generalized Lorenz system by
using sliding mode control method is investigated in this paper. Two
sliding mode control methods are proposed to synchronize the
noise-perturbed generalized Lorenz system. Numerical simulations are
also provided for the illustration and verification of the methods. 相似文献

1 IntroductionConsider a Hamiltonian system with small perturbationwhere E is a small parameter. H(x, y), P(x, y) and Q(x, y) are all real polynimials of x and ywith degH = n 1, degP degQ 5 n. We suppose there is a fandly of ovals r(h) C {H(x, y) = h}for h E (ho, h1).The nunther of limit cycles of (1.1). l which tend to some r(h) as e -- 0, is closely relatedto the number of isolated zeroes of Abelian integraJThe next problem is to determille the lowest bound of the isolated zeroes of M… 相似文献

This article investigates the consensus problem of the second-order multi-agent systems with an active leader and coupling time delay in direct graph. One decentralized state control rule is constructed for each agent to track the active leader and it is proved that the proposed control scheme enables the consensus to be obtained when the adjacency topology is fixed/switched. Simulation results show effectiveness of the proposed theoretical analysis. 相似文献

A synchronization method is proposed for a class of chaotic systems which can be translated into the strictfeedback form.This approach needs only a single controller and turns out to be globally exponentially asymptotically stable.The effectiveness of this approach has been demonstrated with the Rossler chaotic system. 相似文献

The method for controlling chaotic transition system was investigated using sampled- data . The output of chaotic transition system was sampled at a given sampling rate , then the sampled output was used by a feedbacks subsystem to construct a control signal for controlling chaotic transition system to the origin . Numerical simulations are presented to show the effectiveness and feasibility of the developed controller. 相似文献
