Abstract
(DE)
Die Erfindung betrifft eine Regelstruktur für den Verstellmotor (8) eines elektrischen Nockenwellenverstellers (6) eines Verbrennungsmotors (1) mit einem Regler (19), der Messsignale des Verbrennungsmotors (1) zu Steuerdaten für den Verstellmotor (8) verarbeitet. Ein Regler (19), der auch bei einem Nullwert des Eingangs-Differenzsignals sinnvolle Werte für die Sollverstelldrehzahl des Verstellmotors (8) aufweist, wird dadurch erreicht, dass dem Ausgangssignal (20) einer geregelten Solldrehzahl das Signal einer ungeregelten Drehzahl (21) aufgeschaltet wird.
(EN)
The invention relates to a control structure for the adjusting motor (8) of an electric camshaft adjuster (6) in an internal combustion engine (1). Said control structure comprises a controller (19) which processes measuring signals of the internal combustion engine (1) to control data for the adjusting motor (8). A controller (19) which has meaningful values for the adjusted setpoint rotational speed of the adjusting motor (8) even when the input differential signal has a zero value, is obtained by applying the signal of an uncontrolled rotational speed (21) to the output signal (20) of a controlled setpoint rotational speed.
(FR)
L'invention concerne une structure de régulation pour le servomoteur (8) d'un dispositif de réglage d'arbre à cames (6) d'un moteur à combustion interne (1), qui comprend un régulateur (19) qui traite des signaux de mesure du moteur à combustion interne (1) pour les transformer en données de commande destinées au servomoteur (8). On obtient un régulateur (19), qui même pour une valeur zéro du signal différentiel d'entrée présente des valeurs significatives pour le nombre de tours de réglage de consigne du servomoteur (8), par le fait que le signal d'un nombre de tours non régulé (21) est ajouté au signal de départ (20) d'un nombre de tours de consigne régulé.
