英文摘要

      In this paper:a new identification technique is presented. The new technique uses both steady-state and dynamic information to identify the nonlinear gain and impulse responses of linear subsystem of the Hammerstein system， respectively， and the estimates obtained are of strong consistence. Besides， the paper also studies the asymptotic distributions and convergence rate of es-timation error of nonlinear gain. Simulation results show that the new technigue is very efficient and practical.
