摘要
采用分数阶T-S模糊模型对分数阶超混沌系统建模,采用并行分布补偿方法设计模糊控制器,通过适当设置状态反馈矩阵使得闭环极点位于稳定区域内,从而保证闭环系统满足渐近稳定性条件,通过设置同步状态反馈矩阵实现两个具有不同初始条件的分数阶Rossler超混沌系统的同步,数值仿真结果表明该方案的效果十分理想。
The fractional-order hyperchaotic systems are modeled using fractional-order T-S fuzzy model.The fuzzy state feedback controller is designed by using parallel distributed compensation technique.The closed loop poles are placed inside the stability cone through setting the state feedback matrix properly,which guarantees the stability condition of closed loop systems.The syn- chronization of two fractional Rossler hyperchaotic systems with different initial states is achieved through setting the synchronization state feedback matrix.The effectiveness of the proposed scheme is demonstrated by numerical simulation results.
