Lag Synchronization for Fuzzy Chaotic System Based on Fuzzy Observer
-
摘要: 引入了一种新的模糊观测器分析混沌系统的同步,构造了一种基于模糊观测器的驱动-响应延迟同步结构,利用Liapunov稳定性定理为其设计了一个简单的延迟同步标准,并证明对应控制增益矩阵可以通过LMI方法获得.最后,通过Chen系统的例子验证所得结果的有效性.Abstract: A new fuzzy observer for lag synchronization was given.By investigating synchronization of chaotic systems,the structure of drive response lag synchronization for fuzzy chaos system based on fuzzy observer was proposed,and a new lag synchronization criterion was derived by Liapunov sta bility theorem,in which control gains are obtained by LMI condition.The proposed approach is applied to well known Chens systems.And simulation example is presented to illustrate its effectiveness.
