Abstract
A control system is for accelerating stabilization of a chaotic state of a controlled system into a desired periodic state. In the control system, the SOGY algorithm is extended to permit selection of a region on a chaotic attractor as a target, so that the SOGY algorithm can be successfully combined with the OGY algorithm for the purpose of stabilization of the controlled system in the periodic state. Also, the method of nonlinear prediction is introduced so as to secure the effectiveness of the SOGY algorithm. Further, an uncertainty of prediction is taken into consideration so as to eliminate unnecessary control and to improve the effectiveness of the SOGY algorithm.
