英文摘要

      In this paper,for a class of bilinear Hammerstein model which has characteristic of static nonlinear gain zero point symmetry,an integrated identification method combined steady state with dynamic identification is introduced. The strong consistemt estimates of steady state model are obtained by using steady state data. The estimates of nonlinear gain are obtained by using steady state model. The consistent estimates of the bilinear unknown parameter of the bilinear Hammerstein model are obtained. The efficiency and applicability of this estimate technique is demonstrated by simulation results.
