Evolutionary Identification of Block-Structured Systems

Abstract

The identification of a nonlinear model often involves a significant amount of user interaction. The proposed SADE evolutionary algorithm-based identification approach for block-structured systems reduces this user interaction to a minimum. This is illustrated in this paper for the Wiener-Hammerstein class of systems. On top of this, most of the assumptions and limitations on the considered Wiener-Hammerstein system class can be omitted compared to the popular BLA and correlation based approaches. The developed identification algorithm is applied on the 2009 Wiener-Hammerstein benchmark to illustrate its good performance.
