A torsional mode damping controller system is connected to a converter or placed inside the converter. The converter is driving a drive train including an electrical machine and a non-electrical machine. The controller system includes a first input interface configured to receive a first digital signal from a first phase lock device or a first dynamic observer, a second input interface configured to receive a second digital signal from a second phase lock device or a second dynamic observer, and a controller connected to the first and second input interfaces. The controller is configured to receive the first and second digital signals, compare the first digital signal with the second digital signal, generate control data for a rectifier and/or an inverter of the converter, and send the control data to the rectifier and/or to the inverter. |
