Abstract

Described is a method for processing and/or predicting flow data of a flowing medium, in which from values of at least one flow parameter which are successively measured on a continuous basis at one or various locations in the medium, said flow parameter being characteristic for the speed of the medium, a time series is formed and updated which is subjected to a nonlinear deterministic prediction procedure on the basis of a locally constant phase space model for generating prediction values for the respective subsequent flow parameters, wherein a predetermined control signal is generated if the prediction values are characteristic for an impending change in the flow speed. Applications of the method for controlling wind generators are also described.
