Recently, the research of chaos has come into vogue. Chaotic behavior is observed in many different fields and applications of chaos for these situations are required. In this paper , the 3-dimentional chaotic trajectory is controlled by using poincare surface and the plural Unstable Periodic Regions(UPR) when the chaotic map is unknown. Furthermore we propose a new concept of Double Poincare map method for the estimating chaos trajectory and can get the good estimated value. Finally, we confirm the effectiveness of this method with numerical experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
