4.10.2 Torque ripple compensation

Synchronous motors normally have ripple torques. This can cause speed variations in the
speed control, because the torques cannot be adjusted quickly enough. The controller
can compensate these ripple torques. A feedforward of an additional current torque is
generated, in which an additional current torque is generated in dependence of an electric
or mechanic angle.
Figure 222:
Before operation of the controller, an identification of the torque ripples can be made. The
required currents are measured here and then are preprocessed. Then the additional cur-
rent set values are saved in the table.
