【Abstract】 For the robust modeling problem of weakly nonlinear system, based on Volterra series, a robust identification method for generalized frequency response function is presented by use of set membership identification theory. Then a systematic robust modeling method for weak nonlinear system is raised. Simulation results show its effectiveness.更多还原
