На основе экспериментальных данных входа-выхода процесса производства карбамида, оцениваются коэффициенты рядов Вольтерра посредством фильтров Лагерра и метода наименьших квадратов.</p></abstract><trans-abstract xml:lang="en"><p>The identification of nonlinear systems using Volterra-Laguerre model is a method for estimating the dynamic coefficients of Volterra series.
