文章提出了1个四维分数阶超混沌系统,系统的每个方程中都含有1个三次非线性交叉乘积项,具有真正的四翼混沌吸引子。利用非线性反馈控制法设计了控制器,得到了使响应系统与驱动系统实现同步时反馈控制增益的取值范围,数值仿真结果验证了该方法的可行性。
文章提齣瞭1箇四維分數階超混沌繫統,繫統的每箇方程中都含有1箇三次非線性交扠乘積項,具有真正的四翼混沌吸引子。利用非線性反饋控製法設計瞭控製器,得到瞭使響應繫統與驅動繫統實現同步時反饋控製增益的取值範圍,數值倣真結果驗證瞭該方法的可行性。

The fractional order four‐dimensional hyperchaotic system which consists of a true four‐winged cha‐otic attractor is proposed in this paper .There is a cubic nonlinear cross product term in each equation .Using the method of nonlinear feedback control synchronization , the controller is designed for synchronizing the drive system and the response system ,and the range of feedback gain is derived .T he results of numerical sim‐ulations are provided to show the effectiveness of the proposed method .
