An electromechanical engine valve actuation system 10 is provided including a loss compensation controller 16, a first actuator 18, a second actuator 20, an armature element 26 and a motion detector 32. The loss compensation controller 16 calculates the mechanical losses of the armature element and controls the first actuator 18 and the second actuator 20 in response to the mechanical losses in order to reduce the impact of the armature element 26.
