Abstract

In a method and a device for pulse width modulated (PWM-) activation of an electrical drive motor (2) of an adjustment arrangement based on a reference of the mechanical system of the adjustment arrangement that corresponds to a relationship between the force (F) on the drive motor (2) and the adjustment path (s) or the adjustment time (t) of the adjustment arrangement stored in a memory (9), an anticipated future force value (F(t+t0)) is determined based on the reference of the mechanical system in order to adjust the PWM activation in advance by utilizing this future force value such that motor synchronization fluctuations can be prevented upon anticipated mechanical fluctuations in the adjustment arrangement.
