Using Electro-mechanical Actuator (EMA) in rudder-surface can reduce aircraft weight and wing area, and lower costs. If EMA is damaged, the flight performance will be influenced and causes serious accidents. Redundancy control can effectively improve the reliability of EMA, but it has force fight. At the same time, the permanent magnet synchronous servo motor plays a key role in EMA, so the motor position sensor failure expands the force fight, reduces the control effectiveness, and affects aircraft operational safety. To solve these problems, this paper proposes a dual-redundant electro-mechanical actuators force fight reduction control based on position sensor fault-tolerant, which considering the mechanism of force fight and motor parameters mismatch. Finally, verified the effectiveness of proposed method.
