Abstract

Sistema di posizionamento automatico in cui un elemento divisore suddivide lo spazio compreso tra la posizione iniziale e la posizione finale richiesta in un numero prefissato di posizioni di misurazione ben definite ad intervalli prefissati e non necessariamente costanti, in corrispondenza delle quali posizioni mezzi di misurazione determinano i valori effettivi di tempo, di velocità e di accelerazione e quindi l'entità dei disturbi come differenza di accelerazioni mentre opportuni mezzi di calcolo definiscono la variazione di accelerazione da dare all'organo di movimentazione per compensare detti disturbi e ripristinare la legge del moto prefissata; sono inoltre descritti due diversi mezzi di calcolo.
