Publication number: 20230139395Abstract: A method is for operating a valve that includes a linearly movable control slide, at least one solenoid, and a position sensor. The linearly movable control slide is preloaded by at least one spring in a direction of a zero position. The at least one solenoid is coupled to the control slide in such a way that the control slide can be moved away from the zero position by application of current to the solenoid. The position sensor is configured to measure an actual instantaneous position of the control slide. Each solenoid is assigned a current control device configured to influence a current through the relevant solenoid based on an instantaneous current control variable. The instantaneous current control variable is dependent on a quasi-periodic dither current control variable. The method also includes calculating an actual dither amplitude from the actual instantaneous position using a band-pass filter.Type: ApplicationFiled: October 28, 2022Publication date: May 4, 2023Inventors: Ingo Kallfass, Steffen Knapper, Reiner Kunz
