一种民用飞机电作动舱门集中式控制方案研究

在未来飞机多/全电化和机电综合管理的发展趋势下，舱门作动器逐渐由机电作动取代了传统的液压、机械作动。针对目前民用飞机舱门分散式独立控制杂、乱、散的局面，提出一种用于电作动舱门的集中式控制方案。对该集中式控制方案下如何实现电机的伺服控制、舱门的并行控制以及接近传感器感应距离值的修改进行设计，并搭建舱门作动系统模拟装置及电机加载试验平台，对集中式控制的架构及电机伺服控制进行试验验证。结果表明：本文提出的电作动舱门集中式控制方案是可行的，且该方案能够大幅减少舱门线缆数量，降低舱门系统的复杂度，提高系统可靠性及可维护性。

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

Under the development trend of multiple/full electrification of aircraft and integrated electromechanical management, the door actuator gradually replaced the traditional hydraulic and mechanical actuation by electromechanical actuation. Aiming at the current situation where the cabin doors of civil aircrafts 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 were designed, and the simulation device of the hatch actuation system and the motor loading experiment platform were built. The control structure and motor servo have been experimentally verified. The research results show that the centralized control scheme of electrically actuated hatch can greatly reduce the number of hatch cables, reduce the complexity of the hatch system, and improve the reliability and maintainability of the system.
