Beschreibung
Zusammenfassung:	A method and system for use with actuation system (10) to control a plurality of vanes (39) disposed within a turbine engine, wherein a vane position sensor (38) provides a vane position signal corresponding to a vane position of the plurality of vanes (39), the actuation system (10) includes a plurality of motors (26) engaged in response to the vane position signal, and a differential gearbox (22) having a plurality of inputs (23) operatively coupled to the plurality of motors (26) and an output (25) operatively coupled to the plurality of vanes (39), wherein an output (25) speed of the output is a sum of a plurality of input speeds of the plurality of inputs (23).
