A Concept of Automatic Tuning of Longwall Scraper Conveyor Model [PDF]

open access: yesAnnals of Computer Science and Information Systems, 2016
The modeling of machines and their operation modes is a key approach for optimization of their performance as well as for avoiding unwanted operational states which may lead to the occurrence of faults, and finally, to the breakdown. The developed model of a machine should be always parametrized, i.e. the certain number of parameters should be selected
