Abstract (en)
[origin: WO2017076965A1] The invention relates to a method for controlling a hydraulically actuated drive unit (1-3) in particular for a valve, wherein the adjustment velocity (v1) is determined at least over part of the adjustment travel of the drive unit and is compared with a specified target adjustment velocity (v), whereupon, in the case of a difference between the actual value (v1) and the target value (v) of the velocity, the control of the drive unit (1-3) is changed in such a way that the adjustment velocity (v') of the drive unit is adjusted to the target value (v).
