Structure Identification of Block-Oriented Models Based on the Volterra Kernels

Abstract

The paper summarizes the block-oriented models having only one multiplier and the Volterra kernels describing them. It is pointed out that while the Volterra kernels can easily be derived from the block-oriented models, the structure and the parameters of the block-oriented models cannot be computed in a trivial way from the estimated Volterra kernels. Both graphical and analytical procedures are recommended for the structure identification. The method is supported by simulation examples.
