Title (EN) DIGITAL MOTOR CONTROL FOR POSITIONING SYSTEM
(FR) COMMANDE DIGITALE DE MOTEUR POUR UN SYSTEME DE POSITIONNEMENT
Abstract: front page image
(EN)A digital motor control positioning system, and method, in which lead screw position (12) is measured by an encoder (26), and the error between that position and the destination is measured (28), either continuously or repetitively, to provide digital, distance-representing control pulses to the motor (14, 16). In the final, settling-in portion of motor movement, it is successively started and stopped to provide incremental distance movements, which preferably are reduced in size as the destination is approached.
(FR)Systeme et procede de positionnement a commande digitale d"un moteur dans lequel la position de la vis-mere (12) est mesuree par un codeur (26) et l"erreur entre cette position et la destination est mesuree (28) soit de facon continue soit repetitive, pour fournir au moteur (14, 16) des impulsions digitales de commande representant la distance. Dans la partie finale du mouvement du moteur, celui-ci est mis en route et arrete successivement pour produire des deplacements de distance par increments, deplacements dont la longueur est reduite de preference au fur et a mesure que la destination est approchee.
