民用飞机偏航控制系统设计策略研究

偏航控制系统是保证飞机安全飞行的关键系统,其性能优劣不仅直接影响飞机的操纵品质和性能,失效状态下还会危及飞机的飞行安全,方向舵作为偏航控制主要操纵面,其权限管理、余度配置以及稳定能力的设计都需要高的可靠性和安全性；如果使用闭环控制回路,设计措施来避免系统与飞机弹性模态之间的不良耦合是必须的。

Control Strategy Research of Yaw Control System for Civil Aircraft

The yaw control system is the critical system to ensure the safe-flight of civil aircraft. Its performance not only directly affects the control quality and performance of the aircraft, but also endangers the flight safety of the aircraft in the failure state. As the main control surface of the yaw control, the authority management, redundancy configuration and stability design of the rudder need high reliability and safety. It is necessary to design measures to avoid the bad coupling between the system and the elastic mode of the aircraft.
