摘要
运用Adomian分解法对一类具有正弦非线性项的新超混沌系统进行分数阶分析,对该系统进行了稳定性分析,并利用相图、分岔图以及Lyapunov指数谱对系统参数变化时的动力学行为进行了分析.最后,设计了驱动系统的自适应同步控制器.仿真结果验证了该系统周期到混沌运动的丰富的动力学特性及驱动系统自适应同步控制的有效性.
The adomian decomposition method is used to analyze the stability of a class of new hyperchaotic systems with sinusoidal nonlinear terms.The phase diagram, bifurcation diagram and Lyapunov exponent are used to analyze the dynamic behavior of the system with varying parameters. Finally, an adaptive synchronization controller for the drive system is designed. The simulation results verify the dynamic characteristics of the system from period to chaos and the effectiveness of the adaptive synchronization control.
