| Abstract: | Finite impulse response digital filter was used to stabilize the unstable periodic orbits (UPO) embedded in a chaotic attractor of differential dynamic system and two-dimensional map; and thus high periodic orbits was controlled. As examples we studied the Lorenz system and Henon map. A preliminary analysis and results of numerical analogy are presented. The advantages of this method are that it does not need to know the linear properities and the periodicity about a UPO or that of the UPO extracted from the chaotic attractor. The choice of control parameter is independent of the controlled chaotic system. |
