Keywords: active/active, dissimilar, force equalization, force fighting, redundant actuator

The force fighting is a big problem for the redundant active/active position control system involving dissimilar technology actuators. The studied actuation system is composed by one SHA and one EMA, some force equalization control strategies are proposed, simulated, experimented and compared.
