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.
A method for pulse width modulated activation of an electrical drive motor of an adjustment arrangement on the basis of a reference, stored in a memory, of the mechanical system of the adjustment arrangement, said reference corresponding to a relationship between the force at the drive motor and the adjustment path or the adjustment time of the adjustment arrangement, the method comprising:
An apparatus for PWM activation of an electrical drive motor of an adjustment arrangement on the basis of a reference, stored in a memory, of the mechanical system of the adjustment arrangement, which reference corresponds to a relationship between the force at the drive motor and the adjustment path or the adjustment time (t) of the adjustment arrangement, the apparatus comprising:
A system for pulse width modulated activation of an electrical drive motor of an adjustment arrangement on the basis of a reference, stored in a memory, of the mechanical system of the adjustment arrangement, said reference corresponding to a relationship between the force at the drive motor and the adjustment path or the adjustment time of the adjustment arrangement, comprising a processor programmed to determine an expected future force value on the basis of the reference of the mechanical system in order to set the PWM activation in advance using this future force value in such a way that, in the event of expected mechanical fluctuations, of the adjustment arrangement, fluctuations in the synchronized operation of the motor are avoided.
