Abstract

Μέθοδος που περιλαμβάνει τον καθορισμό μιας ρύθμισης ελέγχου και την επιλεκτική διακοπή της ταλάντωσης ενός ταλαντωτή μετά από μια χρονική περίοδο. Ο ταλαντωτής είναι ρυθμισμένος ώστε να παραμένει σε ενεργή κατάσταση μετά τη χρονική περίοδο. Η μέθοδος περιλαμβάνει επιπλέον την εφαρμογή της ρύθμισης ελέγχου στον ταλαντωτή.
