摘要
研究了一类不同分数阶统一混沌系统间的修正广义函数射影同步.利用分数阶微分非线性系统Lyapunov稳定性理论以及分数阶微分不等式,对于参数已知和参数未知的一类不同分数阶统一混沌系统,分别设计两种新的控制器来实现混沌系统间的修正广义函数射影同步.通过数值仿真,结果证明了该方法的有效性.
A modified general functional projective synchronization in a class of different fractional-order unified chaotic systems is investigated.Two new control schemes are presented to bring the different fractional-order unified chaotic systems into a modified generalized functional projective synchronization based on the Lyapunov stability theory and the fractional-order differential inequality.Numerical simulations are given to illustrate the effectiveness of the method presented.
