摘要: 该文在将混沌系统分为线性与非线性两部分的基础上,利用反馈控制及参数变换,提出了一种新的混沌广义同步方法。该方法基于线性变换,把系统广义同步问题转化为同步误差系统的稳定性问题,并给出了广义同步存在的条件。该方法可以通过配置同步速度,改善混沌广义同步的性能。且不受混沌系统线性部分稳定性的限制,扩大了混沌广义同步的通用性。通过对Lorenz系统进行仿真,结果表明该方法具有很好的适用性。Abstract: When the chaotic systems are divided into linear and nonlinear parts, a new approach is presented to realize generalized synchronization of chaotic systems, by using feedback control and parameter commutation. Based on linear transform, the question of generalized synchronization system can be transformed into the stability question of synchronous error system, and the existence condition of GS has been given. Furthermore, favorable performance of generalized synchronization can be improved according to configuration of GS velocity。Expansive generalization can be acquired, without a limit of stability of linear part of the chaotic system. The Lorenz system is taken for illustration and verification,and the results of the simulation indicated that the method is provided of favorable applicability.
