不确定性超混沌系统的积分滑模同步控制研究

摘要

在参数不确定和外部干扰并存的情况下,对基于积分滑模理论的超混沌系统同步方法进行了研究.该方法利用驱动系统和响应系统间的同步误差建立比例积分滑模函数,并根据滑模函数推导出用于同步控制的滑模控制器.仿真结果证明了该同步控制方法的有效性和鲁棒性.该研究结果为超混沌系统保密通信的同步方案研究提供了参考.%The synchronous method based on integral sliding mode theory for hyper-chaos system is researched with consideration of both uncertain parameters and external interference exists. The proportional and integral sliding function is established by using the synchronous error between drive system and response system, and the sliding controller used for synchronous control is derived in accordance with the sliding function. The results of simulation verify the effectiveness and robustness of this synchronous control method. The research achievements provide good reference for studying synchronous strategies of secure communication of hyper-chaos system.
