摘要:
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.

A chaotic character evaluating apparatus includes a processor for predicting future variation in sequential data and a processing for determining a degree of accuracy of the prediction, a processor for predicting variation of the sequential data in reverse and a processor for determining a degree of accuracy of the prediction, and a processing for comparing the degrees of accuracy with each other. If the degrees of the accuracy differ from each other, the variation of the sequential data is determined to be attributable to chaos, while when the degrees of accuracy are substantially equal to each other, the variation in the sequential data is determined to be attributable to noise. Further, a control apparatus for generating a control value from a feedback signal output from an object under control and having chaotic components eliminated is realized. Thus, it is possible to easily and accurately determine whether variation in the sequential data is attributable to chaos or noise.
