Title (EN) PROGRAMMABLE DUAL-PHASE DIGITAL MOTOR CONTROL WITH SLIDING PROPORTIONALITY
(FR) COMMANDE DE MOTEUR NUMERIQUE PROGRAMMABLE A DOUBLE PHASE ET A PROPORTIONNALITE EN DEVIATION
Abstract:
(EN) A digital motor control is described which is programmable and has dual digital phase with sliding proportionality such that the motor control adaptively alters a speed of a motor by both changing sign and altering motor speed proportionally to an amount of motor speed error.
(FR) L'invention concerne une commande de moteur numérique programmable à double phase et à proportionnalité en déviation, qui permet un réglage adaptatif de la vitesse du moteur selon une double opération: changement de signe et modification de la vitesse du moteur proportionnellement par rapport à un degré d'erreur dans la vitesse du moteur en question.
