Prenosivi elektronski sistem za karakterizaciju i estimaciju parametara senzora / Portable electronic system for characterization and parameter estimation ofsensors

Simić Mitar 16 November 2017 (has links)
<p>Jedan od doprinosa ove disertacije je realizacija modela prenosivog<br />mernog sistema za karakterizaciju senzora uz mogućnost daljinskog<br />pristupa rezultatima merenja. U LTCC tehnologiji je fabrikovan<br />senzor za merenje pH vrednosti, na bazi TiO2 filma na alumina<br />substratu, koji je karakterisan razvijenim mernim sistemom. Izvršena<br />je i obrada podataka dobijenih prilikom karakterizacije senzora<br />formiranjem polinomske statičke karakteristike i modelovanjem<br />senzora ekvivalentnom električnom mrežom. Predložen je novi<br />neiterativni metod estimacije vrednosti parametara modela koji, u<br />poređenju sa metodom najmanjih kvadrata, omogućava jednostavniju<br />estimaciju uz kraće vreme izvršavanja.</p> / <p>One of the contributions of this research is a model of the portable electronic<br />measurement system for sensors characterization with remote access to the<br />measurement results. In LTCC technology a TiO2-based pH sensor is<br />fabricated on the alumina substrate and it was characterized with developed<br />measurement system. Experimentally obtained data was analyzed with<br />polynomial sensor characteristic as well as equivalent electric circuit (model).<br />A new method for parameter estimation of the used 2R-1C model is<br />presented and comparison with complex nonlinear least squares was<br />performed.</p>
