Abstract

In a method for synchronizing drive units, a target value of the speed of each drive unit of a plurality of drive units speed is computed by determining the product of a maximum speed of the drive unit, a unit-dependent normalized ratio value of the drive unit, and a synchronization factor which is identical for all drive units. The ratio value defines the relative speeds of the individual drive units. Changing the synchronization factor causes synchronous speed changes of the drive units. As a result, a lasting synchronization can be realized across the entire speed spectrum.
