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 Poincar_??_ 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.
