Description
  • Článek prezentuje nový přístup k modelování fokusační chyby v DVD přehrávači aplikovaný na průmyslový systém, vyvinutý v laboratořích STMicroelectronics. Nejprve jsou navrženy dva matematické modely založené na astigmatické metodě a optogeometrické analýze. Je též sestaven numerický model. Následně je užito proložení experimentálně získaných dat křivkou a odhadnuty neznámé parametry modelu. Tyto parametry budou následně zahrnuty do řídící smyčky pro zlepšení chování. (cs)
  • This paper presents a new approach to focus error modelling in a DVD player, applied to an industrial system, developed in STMicroelectronics laboratories. First, two mathematical models, based on astigmatic method and on opto-geometrical analysis, are given. A numerical model is given too. Then a curve fitting method is applied, using real data from the industrial system, in order to estimate the unknown parameters of these models. They will be further included in the focus error control loop in orderr to improve the performance analysis.
