【摘要】 研究了具有四个未知参数的超混沌 Lü系统的自适应控制同步问题。基于 Lyapunov 稳定理论,提出了采用两个控制器使参数全部未知的超混沌 Lü系统达到自适应同步的新方法。它改进和完善了高秉建等人采用4个控制器和贾贞等人采用3个控制器自适应同步超混沌 Lü系统的工作。该方法通过增大控制参数的数值,可以得到更快的参数自适应律和同步响应速度。数值仿真结果验证了该方法的有效性和可行性。更多还原

【Abstract】 Adaptive synchronization of hyperchaotic Lü system with four uncertain parameters is studied.Based on adaptive theory and Lyapunov stability theory,the paper presents a new adaptive control method for the synchronization of hypcrchaotic Lü System with fully unknown parameters by employing two controllers.The obtained results here improve and extend the work of Gao Bing-jian et al.,with four controllers and Jia Zhen et al.,with three controllers.The method can obtain a faster update law of unknown parameters and a faster synchronization response rate by increasing control parameters.Numerical simulations are provided to show the effectiveness and feasibility of the developed method.更多还原
