Research on a Centralized Control Scheme of Civil Aircraft Electromechanical Actuating Cabin Door

Abstract

Under the development trend of multiple/full electrification of aircraft and integrated electromechanical management,the traditional hydraulic and mechanical actuation is gradually replaced by door actuator through electromechanical actuation.Aiming at the current situation where the cabin doors of civil aircraft are controlled separately,chaotically and scattered,a centralized control scheme for electrically actuated cabin doors is proposed.Under the centralized control scheme,how to realize the servo control of the motor,the parallel control of the hatch,and the modification of the proximity sensor sensing distance value is designed,and the simulation device of the hatch actuation system and the motor loading experiment platform are built.The control structure and motor servo control are performed with experiment verification.The results show that the proposed centralized control scheme for electrically actuated doors is feasible,and this scheme can greatly reduce the number of door cables,reduce the complexity of the door system,and improve the reliability and maintainability of the system.
