Combining characteristic numbers to reduce the uncertainty of fractional pole models
Original language description
The paper extends the authors' previous results where the class of all lag/dead time process models (with integer or fractional order poles) is considered in the case that the following characteristic numbers are given: a) one sample of a process frequency response, b) first three moments of the process impulse response. In both cases, the explicit parameterizations of the value set boundary were provided. In this paper, the simultaneous knowledge of the characteristic numbers a) and b) is assumed and the corresponding upper hard bound of the value set boundary is described. It is shown that combining experimental data a) and b) leads to the significant reduction of a model uncertainty in the frequency domain. Additionally, the investigated results areapplied to the robust controller design.

Kombinování charakteristických čísel pro snížení neurčitosti fractional-order-pole modelů
Czech description
Článek navazuje na předchozí výsledky, kde byla uvažována pro identifikaci fractional-order-pole modelů charakteristická čísla a) body frekvenční charakteristiky b) momenty impulsní funkce. Je zde ukázáno, že kombinace těchto charakteristických čísel vede k významnému zmenšení neurčitosti ve frekvenční oblasti.
