Title (EN) POSITIONING SERVOCONTROLLER
(FR) SERVOMECANISME DE POSITIONNEMENT
Abstract: front page image
(EN)A positioning servocontroller performs optimum positioning simply by adjusting control gain. A positioning servocontroller comprises speed feedforward control means (22) that uses a speed command corresponding to the sum of a position deviation and a first feedforward compensation; acceleration feedforward means (23) that uses an acceleration command corresponding to the sum of a speed deviation and a second feedforward compensation obtained by amplifying and differentiating the first feedforward compensation amount; and a torque amplifier (3) that drives an object based on an acceleration deviation as a torque command. The first feedforward gain and the second feedforward gain are derived from a function that uses the values of control gain as arguments.
(FR)L'invention concerne un servomécanisme de positionnement optimal par simple réglage du gain de commande, qui comprend un système de commande anticipative de vitesse (22) dont la commande correspond à la somme d'un écart de position et d'une première compensation anticipative; un système de commande anticipative d'accélération (23) dont la commande correspond à la somme d'un écart de vitesse et d'une seconde compensation anticipative obtenue par amplification et différenciation de la première compensation; et un amplificateur de couple (3) entraînant un objet sur la base d'un écart d'accélération en tant que commande de couple. Les premier et second gains anticipatifs sont dérivés d'une fonction qui utilise les valeurs de gain de commande comme arguments.
