Abstract

Die Erfindung betrifft ein Verfahren zur Bewegungssteuerung eines Ankers (4d) eines elektromagnetischen Aktuators (4), insbesondere zur Betätigung eines Gaswechsel-Hubventiles (1) einer Brennkraftmaschine, wobei der Anker (4d) oszillierend zwischen zwei Elektromagnet-Spulen (4a, 4b) jeweils gegen die Kraft zumindest einer Rückstellfeder (2a, 2b) durch alternierende Bestromung der Elektromagnet-Spulen bewegt wird, und wobei mit einer Annäherung des Ankers an die zunächst bestromte Spule während des sogenannten Fangvorganges die an der den Anker einfangenden Spule anliegende elektrische Spannung reduziert wird.
Erfindungsgemäß schließt sich an die Fangphase des Fangvorganges eine Bremsphase an, in welcher bis zum Auftreffen des Ankers auf die Spule an diese getaktet elektrische Spannung angelegt wird, wobei die jeweiligen Schalt-Zeitpunkte und das Spannungs-Taktverhältnis von einem Regler anhand einer die Anker-Sollbewegung beschreibenden Solltrajektorie bestimmt werden. Bevorzugt wird getaktet entweder ein betragsmäßig konstanter positiver oder negativer Spannungswert oder der Spannungswert

The invention relates to a method for controlling the movement of an armature (4d) of an electromagnetic actuator (4), in particular for actuating a gas exchange lift valve (1) of an internal combustion engine, the armature (4d) oscillating between two electromagnetic coils (4a, 4b) in each case is moved against the force of at least one return spring (2a, 2b) by alternating energization of the electromagnet coils, and the electrical voltage applied to the coil capturing the armature is reduced when the armature approaches the initially energized coil during the so-called catching process.
According to the invention, the catching phase of the catching process is followed by a braking phase in which, until the armature hits the coil, electrical voltage is applied to the coil, the respective switching times and the voltage-pulse ratio being determined by a controller on the basis of a desired armature movement Descriptive target trajectory can be determined. Preferably, either a positive or negative voltage value that is constant in terms of amount or the voltage value is clocked
