3.4.3.2 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.
