摘　　要：针对统一混沌系统,进一步分析了系统的混沌特性,基于稳定性理论,设计了能实现其反同步控制的非线性控制器。利用李雅普诺夫稳定性理论证明了反同步误差系统是全局渐近稳定的.Matlab数值仿真结果表明,所设计的控制器能有效地实现统一混沌系统的反同步。The unified chaotic system was presented, and its chaos characteristic was analyzed deeply. Suitable nonlinear controller was designed to realize the anti-synchronization. By means of Lyapunov stability theory, it is proved that the dynamics of the anti-synchronization error is globally and asymptotically stable. Numerical simulations by Matlab are provided to demonstrate the validity of the proposed nonlinear controller for achieving the anti-synchronization.
