摘 要: 首先采用时频域转换法,通过整数阶算子拟合分数阶算子的方法逼近,实现了分数阶超混沌Liu系统。接着基于投影同步理论及分数阶系统稳定性理论,采用线性分离的方法实现了含有未知参数的分数阶超混沌Liu系统的投影同步。最后利用Simulink进行数值仿真,仿真结果证明了该同步方法的正确性与有效性。
关 键 词: 控制理论;超混沌Liu系统;分数阶;投影同步;数值仿真

Abstract: In this paper, based on the frequency response of the fractional integral operator, the fractional order Liu hyperchaotic system was realized by using frequency domain approximation. Then the projective synchronization of this fractional order Liu hyperchaotic system with uncertain parameters was realized by the linear separation method based on the theory of projective synchronization and the stability theorem about fractional systems. Finally, numerical simulations were given by using Simulink to verify and test the correctness and effectiveness of the synchronization methods.
Key words: control theory; Liu hyperchaotic system; fractional order; projective synchronization; numerical simulation
