Chaotic Control and Synchronization Up to a Scaling Function Vector

In this paper, Chaotic control and synchronization up to a scaling function vector with uncertain parameters or not are considered. Based on symbolic computation Maple and the chaotic controlling methods: the cascade synchronization approach and active control method, generalized control scheme (GCS) is developed to realize control and synchronization of two identical chen-lee system with uncertain parameters and GCS between the Rucklidge system and the disk dynamo model. Numerical simulations are used to verify the effectiveness of the scheme.
