摘要
针对超混沌Lorenz系统,设计了实现其同步的2种非线性控制器.利用李雅普诺夫稳定性定理,证明了同步误差系统是全局渐近稳定的.Matlab数值仿真结果表明,所设计的非线性控制器能有效地实现混沌同步.
This paper designs two kinds of nonlinear controllers to realize the synchronization of hyperchaotic Lorenz system.. By means of Lyapunov stability theorem, it is proved that the dynamics of the synchronization error is globally and asymptotically stable. Numerical simulations by Matlab are provided to demonstrate the validity of the proposed nonlinear controllers to achieve the chaotic synchronization.
