PROCESS FOR CONTROLLING AN ACTUATOR WHICH CAN BE ADJUSTED BY MEANS OF A PROPORTIONAL VALVE

The invention relates to a process for controlling an actuator which can be adjusted by means of a proportional valve controlled by two control magnets with counteracting control pulses. The phase angle between the control pulses is varied in function of at least one control variable (command variab...

Beschreibung
Zusammenfassung:	The invention relates to a process for controlling an actuator which can be adjusted by means of a proportional valve controlled by two control magnets with counteracting control pulses. The phase angle between the control pulses is varied in function of at least one control variable (command variable, correction variable or difference between the amplitudes or durations of the control pulses), i.e., reduced as the control variable increases. This measure prevents undesirable vibrations of the actuator and noises to which these give rise. Procédé pour la mise au point d'un élément de réglage réglable au moyen d'une soupape proportionnelle susceptible d'être commandée par l'intermédiaire de deux aimants de commande à impulsions de commande agissant en sens inverse. L'angle de phase entre les impulsions de commande est modifié en fonction d'au moins une grandeur d'influence (grandeur pilote, grandeur de réglage ou bien différence des amplitudes ou des durées des impulsions de commande), c.à.d. il est réduit au fur et à mesure que la grandeur d'influence augmente. Cette mesure permet d'éviter des vibrations gênantes de l'élément de réglage ainsi que les bruits qui en résultent.
