RECURSIVE IDENTIFICATION OF HAMMERSTEIN SYSTEMS WITH POLYNOMIAL NONLINEARITIES

Jozef Vörös

   The paper deals with recursive identification of nonlinear dynamic systems using Hammerstein models with two-segment polynomial nonlinearities. A special form of Hammerstein model is considered, which is linear-in-parameters. The proposed algorithm is a direct application of the known recursive least squares method supplemented with the estimation of internal variables.
