| 摘 要： | 针对2个不同的具有复杂动力学行为的新型四维混沌系统的异结构广义同步问题,基于Lyapunov稳定理论,采用自适应控制同步法,通过选择连续可微的非线性广义同步函数,设计自适应控制策略和参数自适应律,实现了2个参数未知的新型四维混沌系统的异结构广义同步以及辨识了未知参数.该方法没有强加在系统的假设条件上,几乎适用于所用的混沌系统.理论推导和数值仿真验证了该方法的有效性.

| Abstract: | For the problem of generalized synchronization for two four-dimensional chaotic systems with different structure and unknown parameters,based on the Lyapunov stabilization theory,and the adaptive control synchronization method,by choosing the continuous and differentiable non-linear function of generalized synchronization,adaptive controller and adaptive law of parameters were given,which makes the different systems reach to generalized syschronization,and identifies the unknown parameters.No restrictive assumption is imposed on the system,thus,the method can be applied to every chaotic system.The simulation results illustrate the efficiency of the method. |
