Electromechanical actuator (EMA) system is the actuator of the aircraft FBW system, is an important part of the flight control system, a development direction of more electric or all electric aircraft. A multi-actuator configuration, in which some (usually three or more) EMAs operated on the same control surface, was provided a comprehensive way to introduce EMAs into primary flight controls, but the problem of un-synchronization was resulted. For this, an improved synchronization control strategy was presented. The synchronization control strategy was implemented by synchronization controllers. The control strategy was synthesized of each advantage of masterslave and equal controls, and improved the performance of synchronization control through optimization of the comparator. The programmable logic cells were based to implement the controller, and the parallel bus technologies were adopted for data exchange. The parallel bus controllers and synchronization control were integrated effectively. The actual application shows that the current controller works well, and the real-time and reliability of the present synchronization controller are improved.
