摘要 对一个四维超混沌系统的的参数辨识问题进行了研究.首先基于非线性动力学理论,利用超混沌吸引子,随不同参数变化的分岔图和Lyapunov指数谱准确地表征了系统的动力学行为.通过两种参数辨识方法,即基于观测器的参数辨识方法和基于自适应控制的参数辨识方法分别实现该系统的所有未知参数的辨识.数值仿真验证了理论分析和数值计算的正确性. This paper focuses on the parameter identification of a new four-dimensional autonomous hyper-chaotic system.The nonlinear dynamical behavior of the system is investigated further.Moreover,the parameter identification of the new hyper-chaotic system with fully unknown parameters is studied by parameter identification observe and the adaptive control.Numerical simulations show that the effectiveness and feasibility of the theoretical analysis and numerical computation.
