Electro-mechanical actuators for large civil aircraft require an operation in active/active mode for certain primary flight control surfaces and thus measures to guarantee synchronous actuator movements. An approach for effective force fight compensation is introduced. The implemented control scheme was validated on a test rig matching the physical properties of a single aisle aircraft aileron.
