摘　　要：运用自适应控制方法,实现超混沌Chen系统的同结构投影同步,并能辨识出响应系统的未知参数。首先通过采用MATLAB进行数字仿真,表明该自适应控制方法的可行性以及系统的参数辨识作用。其次利用EWB仿真设计模拟电路,结果与MATLAB的仿真结果相吻合,从而进一步证明了该自适应控制方法的有效性和系统参数辨识方法。This paper discusses the problem of modified projective synchronization between two identical unknown hyperchaotic Chen systems by using adaptive control, while identifying the unknown parameters of the response system. Firstly, the numerical simulations are given by using Matlab to show the feasibility of the proposed method. As an application, the proposed scheme is then applied to design the analog circuit by EWB, which obtained the same results with that of MATLAB. Finally, the results further demonstrate the effectiveness of the proposed chaos synchronization scheme and parameters identification method.
