摘　　要：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。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. The results of numerical sim- ulations are provided to show the effectiveness of the proposed method.
