| 摘 要： | 对受噪声干扰的超混沌Lorenz-Stenflo系统的同步问题进行了研究.在设计一种新型比例积分滑模流形的基础上,选取了只含一个控制项的滑膜控制器,根据滑模控制理论证明在此控制器下受噪声干扰的超混沌Lorenz-Stenflo系统能实现同步,并用陡峭的连续饱和函数代替不连续的符号函数,消除了同步过程中的抖动.数值模拟结...

| Abstract: | This paper investigates the synchronization problem between two unidirectionally-coupled Lorenz-Stenflo hyperchaotic system with noise perturbation.It is proved theoretically that the synchronization between such noise-perturbed systems can be implemented by choosing a novel proportional-integral sliding mode surface and designing a sliding mode controller.Numerical simulations show the effectiveness of the theoretical analysis,being robust to the dismatched noise disturbances. |
