Ocena propagacji niepewności modelowania przez procedury wyznaczania maksymalnych błędów dynamicznych
Języki publikacji
Abstrakty
The paper discusses the method for modelling linear analogue systems of the second order in the time domain. As a result of such modelling, the parameters of the model and the associated uncertainties are obtained. Procedures for determining the absolute error and the integral-square error are presented. These procedures make it possible to determine precisely such an input signal with one constraint that maximizes an error at the output of the system. Values of the parameters of an example model are determined and the propagation of the uncertainties of modelling results is assessed by the procedures for determining the maximum dynamic errors. The results of calculations presented in the paper were carried out in MathCad15.
W artykule omówiono metodę modelowania w dziedzinie czasu liniowych systemów analogowych drugiego rzędu. Jako wynik takiego modelowania uzyskano parametry modelu oraz związane z nimi niepewności. Przedstawiono procedury wyznaczania maksymalnych błędów dynamicznych dla przypadku kryteriów błędu: bezwzględnego i całkowokwadratowego. Procedury te pozwalają w sposób precyzyjny określić taki sygnał wejściowego z jednym ograniczeniem, który maksymalizuje błąd na wyjściu systemu. Wyznaczono wartości parametrów przykładowego modelu oraz oceniono propagację niepewności wyników modelowania przez procedury wyznaczania maksymalnych błędów dynamicznych. Wyniki obliczeń przedstawionych w artykule przeprowadzono w programie MathCad15.
